About this book
An overview of the book, with source information for further reading.
In his first book in ten years, Martin Seligman, the father of the Positive Psychology movement, presents a paradigm-shifting new theory of what makes a good life.
Moving beyond his own earlier work on "authentic happiness," Seligman argues that well-being is not just about feeling good, but about flourishing. He introduces the five pillars of a flourishing life—Positive Emotion, Engagement, Relationships, Meaning, and Accomplishment (PERMA)—and provides evidence-based exercises to cultivate them. Drawing on large-scale, real-world applications from transforming schools in Australia to building psychological fitness in the entire U.S. Army, *Flourish* is a watershed guide for individuals, communities, and nations to not only relieve suffering but to actively build the conditions for a deeply fulfilling and productive life.

What this book claims, and who wrote it.
- — The book's one-line promise
- — The author and where the book stands
Psychologist Martin Seligman introduces his "Well-Being Theory," arguing that true flourishing comes from cultivating Positive Emotion, Engagement, Relationships, Meaning, and Accomplishment (PERMA), and presents a vision for applying these principles to transform education, the military, health, and public policy.
The need-to-know
Well-Being Theory, with its five PERMA elements (Positive Emotion, Engagement, Relationships, Meaning, Accomplishment), provides a more complete model of what people choose for its own sake than the previous Authentic Happiness Theory. The goal of positive psychology is to increase flourishing, which is measurable and can be systematically built in individuals and institutions. Character strengths (like kindness, perseverance, and curiosity) are the foundational supports that underpin all five of the PERMA elements.
About this guide
The guide describes these challenges, steps and possible outcomes.
Who it is for
You are building a real capability: Flourish.
Challenges
- In practice · Flourishing erodes when it is left to instinct instead of method.

Steps to consider
- 1Master character strengths.
- 2Master grit.
- 3Master positive emotion.
Risks
You stay dependent on instinct, and it fails you when the stakes are highest.
Intended result
Flourishing becomes something you produce by design, not by luck.
Set the record straight
What this book sets straight
The common beliefs this book pushes back on.
The primary goal of psychology, and of life, is to achieve 'happiness,' which is understood as feeling good and being satisfied with your life.
The goal should be to 'flourish,' which is a broader, multi-dimensional construct. Happiness (positive emotion and life satisfaction) is just one of five core elements (PERMA), which also include engagement, positive relationships, meaning, and accomplishment.
People pursue achievement, success, and mastery only as a means to get happiness, meaning, or other life benefits.
Accomplishment is a fundamental human drive pursued for its own sake, even when it brings no positive emotion or meaning, and is therefore a distinct and core element of well-being.
Lasting increases in well-being are not possible because of the 'hedonic treadmill,' where we quickly adapt to positive changes.
Well-being can be lastingly increased. Specific, scientifically-validated exercises (like the 'What-Went-Well' exercise) can produce sustained improvements in well-being and reductions in depression.
The proper focus of medicine and psychology is curing illness and relieving symptoms; health is simply the absence of disease.
Positive physical and mental health are states that are more than the mere absence of illness. They are defined by the presence of positive assets (like optimism, strong relationships, and vitality) that protect against disease and promote longevity.

- Flourish
This section defines meaning as belonging to and serving something larger than yourself, and distinguishes it from pleasure or achievement. You get where to look for it and how to test whether you've found it.
Meaning
The sense of belonging to and serving something that one believes is bigger than the self. This provides a sense of purpose and a rationale for one's life.
Why it matters. Meaning delivers well-being that is durable and independent of mood, providing a rationale for life that pleasant feelings cannot supply.
Myth
Practitioners believe meaning is a private feeling you discover through introspection or attain once you feel your life is significant.
Reality
Meaning is not primarily subjective; it depends on objective attachment to and service of institutions, causes, or people beyond the self — and it can be judged partly by others and by history, not just felt.
- Well-Being Theory (PERMA)Framework — A framework for understanding and achieving a flourishing life.
- Meaning comes from serving something bigger than the self, not from introspective feelings alone.
- Applying signature strengths in service of a larger cause is the concrete route to meaning.
- Meaning has an objective, judgeable component beyond your subjective sense of significance.

- Flourish
This section treats achievement as a well-being element pursued for its own sake, not merely as a means to other ends. You get how to value mastery without collapsing it into money or status.
Accomplishment
The pursuit and attainment of achievement, mastery, competence, or success, often for its own sake. It constitutes the 'achieving life.'
Why it matters. Recognizing accomplishment as intrinsically valued lets you honor the achieving life without mistaking every pursuit for a path to happiness or meaning.
Myth
People assume accomplishment only counts as well-being if it produces positive emotion, meaning, or wealth.
Reality
The book insists people pursue achievement, mastery, and winning for their own sake — the accomplishment element stands as a free-standing route to a full life even when it yields no pleasure or larger purpose.
- Accomplishment is a legitimate, free-standing element of well-being pursued for its own sake.
- Grit and signature strengths are the two main inputs that convert ability into achievement.
- A high-achievement life still needs the other PERMA elements to constitute flourishing.

This section covers the trainable capacity to recover from adversity through realistic, flexible thinking. You get the cognitive technique that interrupts catastrophizing before it spirals.
Resilience
The capacity to bounce back from adversity, trauma, and stress. It involves mental toughness and flexible, realistic thinking that prevents catastrophic thoughts and promotes coping.
Why it matters. Resilience determines whether setbacks derail you or become recoverable, and it can be taught — making it a skill rather than a fixed trait.
Myth
People believe resilience is an inborn toughness you either have or don't, or that it means suppressing negative feelings.
Reality
Resilience is a learnable set of thinking skills built on disputing pessimistic explanatory styles; it works through realistic, flexible appraisal, not forced positivity or gritted-teeth endurance.

- Flourish
This section defines the destination — optimal functioning across all five PERMA domains — and reframes it from a single feeling into a portfolio. You get how to measure it and why no one element suffices.
Flourishing
The ultimate goal of positive psychology, defined as a state of optimal human functioning characterized by high levels across the five PERMA domains of well-being.
Why it matters. Treating flourishing as one thing (usually happiness) leads you to over-optimize a single domain, whereas seeing it as a five-part portfolio directs effort where returns are actually available.
Myth
Practitioners equate flourishing with maximizing life satisfaction or happiness on a single scale.
Reality
Flourishing is a multidimensional construct built from five independently pursued and independently measured elements; each element is chosen for its own sake, and none is reducible to the others, so life satisfaction alone badly undersamples it.
- Flourishing is a five-element portfolio, not a single happiness measure.
- Each PERMA element is pursued for its own sake and measured independently.
- Target your weakest elements to raise overall flourishing most efficiently.

This section extends flourishing into the body, defining health as the presence of assets — not just the absence of disease — and links psychological well-being to longevity and prognosis. You get why building well-being is also a health intervention.
Positive Physical Health
A state of physical well-being that is more than the absence of illness, characterized by assets (subjective, biological, functional) that increase longevity, lower morbidity, and improve prognosis when illness strikes.
Why it matters. If flourishing predicts lower morbidity and better recovery, then psychological interventions become legitimate levers on physical outcomes, not just mood.
Myth
People think health is a medical matter separate from well-being — you address illness with treatment and happiness with psychology.
Reality
Positive health is defined by subjective, biological, and functional assets that actively increase longevity and improve prognosis; well-being is upstream of physical outcomes, so flourishing functions as preventive medicine.
- Positive health is the presence of assets, not just the absence of disease.
- Flourishing predicts greater longevity, lower morbidity, and better recovery when illness strikes.
- Building well-being is a legitimate form of preventive health care.

This section shows you how to identify and deploy your signature strengths rather than treating all 24 traits as equally worth developing. It reframes character from a moral checklist into a leverage system.
Character Strengths
A set of 24 universally valued, positive personality traits, such as kindness, perseverance, and creativity. The book argues that the exercise of one's highest 'signature' strengths is a primary pathway to well-being.
Why it matters. Building well-being on your top strengths compounds returns, while trying to remediate your weakest traits burns effort for marginal gains.
Myth
Practitioners believe self-improvement means grinding on their weakest strengths until they become well-rounded.
Reality
The payoff comes from recasting existing activities so they draw on your top five 'signature' strengths; a strength you already possess and enjoy using generates far more well-being than one you laboriously acquire.

This section separates grit from raw effort or talent and shows how sustained passion for a single long-term aim outpredicts intelligence for high achievement. You get a way to test whether your persistence is actually gritty.
Grit
A specific character trait defined as the combination of very high perseverance and passion for long-term objectives. It is a critical component of effort and a key predictor of high accomplishment.
Why it matters. Without grit, talent stalls at competence; with it, ordinary ability accumulates into extraordinary accomplishment over years.
Myth
People equate grit with just working harder or refusing to quit anything.
Reality
Grit is stamina in service of one durable top-level goal, not indiscriminate stubbornness; it requires knowing which lower goals to abandon so that resources flow toward the one that matters.
- GRIT ScaleTemplate — To self-assess one's level of perseverance and passion for long-term goals.
- Grit = perseverance × passion aimed at one top-level goal, and it predicts achievement beyond IQ.
- Abandoning misaligned subordinate goals is part of grit, not a betrayal of it.
- Measure grit by accumulated deliberate practice, not by how motivated you feel today.

This section covers the pleasant-feeling side of well-being — joy, comfort, warmth — and its real but bounded role in flourishing. You get realistic expectations for how much happiness you can move and how.
Positive Emotion
The experience of pleasant feelings, good moods, and positive affect, such as joy, pleasure, warmth, and comfort. This represents the 'hedonic' or 'pleasant life' component of well-being.
Why it matters. Overinvesting here chases a set-point ceiling, but neglecting it strips out one of the five independently valuable routes to a full life.
Myth
Practitioners treat positive emotion as the whole of happiness and the ultimate scorecard for well-being.
Reality
Positive emotion is only one of five PERMA elements, and it is the most constrained by genetic set-point; many people who flourish score modestly here and compensate through engagement, meaning, or relationships.
- Positive Psychotherapy (PPT) Session OutlineTemplate — To provide therapists with a structured, 14-session template for treating depression by building well-being rather than just alleviating symptoms.
- Positive emotion is one-fifth of well-being, not its definition.
- Savoring and gratitude practices raise positive affect within your set-point range.
- You can flourish with modest positive emotion by strengthening the other four elements.

This section explains flow — total absorption in an activity — and how to engineer it, since it cannot be summoned by wanting it. You get the specific conditions that produce it.
Engagement (Flow)
A psychological state of being completely absorbed in an activity, characterized by intense concentration, loss of self-consciousness, and a distorted sense of time. Also known as 'flow.'
Why it matters. Engagement is assessed only in retrospect and vanishes the moment you monitor it, so knowing how to set its preconditions is the only lever you have.
Myth
People think they can will themselves into flow or relax their way into it.
Reality
Flow arises structurally, not by intention, when a clear-goal activity's challenge slightly exceeds your current skill; it disappears the instant you feel positive emotion or self-consciousness, which is why it must be reported after the fact.
- Flow requires challenge slightly above skill plus clear goals and immediate feedback.
- You cannot force flow, only build the conditions that invite it.
- Signature strengths are the reliable input for reaching engagement.

This section establishes other people as the single most reliable source of well-being and shows how to build the connections that count. You get the mechanics of responsiveness that make relationships positive.
Positive Relationships
The state of having warm, trusting, mutually supportive, and loving connections with other people. The book argues that 'other people' are the single most reliable source of well-being.
Why it matters. Relationships are the highest-return well-being investment available, and how you respond to others' good news predicts relationship survival more than how you handle conflict.
Myth
People assume strong relationships are mainly about supporting each other through hard times.
Reality
The strongest predictor of relationship quality is 'active-constructive responding' to good news — celebrating a partner's wins enthusiastically matters more than comforting them in crisis.
- Other people are the most dependable route to well-being.
- How you respond to good news predicts relationship health more than crisis support does.
- Active-constructive responding is a trainable, high-leverage relationship skill.

What's underneath
What the field takes for granted
Every field runs on assumptions it rarely says out loud — the beliefs its advice quietly depends on. We surface the load-bearing ones, where they hide, and when they break. Most guides never tell you this.
Placing the idea
How it compares — and where else it applies
We don't just explain the idea in isolation. We place it: against the alternative it replaces, and beyond the domain it was born in. That's the difference between knowing a method and knowing when to reach for it.
How it compares
vs Authentic Happiness Theory (Seligman's earlier theory)
Both theories include Positive Emotion, Engagement, and Meaning as key components of a good life. Both are concerned with moving beyond psychology's traditional focus on mental illness.
Well-Being Theory (PERMA) adds Relationships and Accomplishment as two new, independent elements. It changes the topic from 'happiness' to 'well-being,' and the goal from increasing 'life satisfaction' to increasing 'flourishing.' Well-being theory also allows for objective measures, whereas Authentic Happiness relied solely on subjective self-report.
This book presents Well-Being Theory as a more complete and accurate account of what people choose for its own sake, moving away from a 'monism' of happiness toward a pluralistic model of flourishing.
vs Traditional Psychology and Psychiatry ('psychology-as-usual')
Both acknowledge the reality of mental suffering and the need to alleviate it.
Traditional psychology's goal is to move people from a state of suffering (e.g., -8) to a neutral state (0). Positive psychology's goal is to move people from a neutral state (0) to a state of flourishing (+8), and also argues that building positives is an effective way to treat suffering.
This book argues for supplementing, not replacing, the traditional disease model. It proposes that building strengths and well-being (the 'enabling conditions') is a necessary and distinct process from simply undoing pathology (the 'disabling conditions').
Where else it applies
The model, taken beyond its home domain
Business and Management
The book proposes a 'Positive Business' model where the goal is not just profit, but also fostering the PERMA elements for employees. Techniques like the Losada Ratio and Appreciative Inquiry can be used to improve team dynamics and productivity.
Medicine and Public Health
The book outlines 'Positive Health,' a new paradigm focused on building health assets (like optimism, exercise) to prevent illness, rather than just treating disease. This could shift medical practice and public health policy toward proactive well-being initiatives.
Coaching
Positive psychology provides a scientific backbone for the unregulated coaching industry, offering evidence-based interventions (like signature strengths exercises) and a coherent theory (PERMA) to structure coaching engagements.

Read it closely
The book, examined
Not a summary — a close analytical reading: how the book is built, what it leaves open, and where it falls short.
How it’s built — the argument in order
- 01Revising the theory: from Authentic Happiness to Well-Being — Seligman opens by critiquing his own earlier monism—that happiness (life satisfaction) is the sole target—and argues it collapses too much into mood. He replaces it with Well-Being Theory, a construct measured by multiple independent elements, establishing why 'flourishing' rather than 'feeling good' should be the goal.
- 02Defining the five elements (PERMA) — Lays out Positive Emotion, Engagement, Relationships, Meaning, and Accomplishment as the measurable pillars, each pursued for its own sake, with character strengths as the underpinning supports. Provides evidence-based exercises (e.g., gratitude, signature-strengths use) to build each.
- 03Achievement, grit, and the anatomy of accomplishment — Argues extraordinary achievement equals skill multiplied by effort, with self-discipline and grit as the decisive effort variables, decoupling success from raw IQ/talent alone.
- 04Applications at scale: education and the military — Presents Positive Education programs (Australian schools, Penn Resiliency) to prevent depression and aid learning, and the U.S. Army's Comprehensive Soldier Fitness program as large-scale demonstrations that well-being skills can be taught institutionally.
- 05Positive physical health — Marshals evidence that optimism and positive states have measurable biological effects—protection against cardiovascular disease, infection, and mortality—extending positive psychology into medicine.
- 06Public policy and national well-being — Concludes with a call to supplement GDP with a 'dashboard' of well-being accounts, so policy targets flourishing, ending with the aspiration of raising global flourishing.
What it leaves unsolved
How exactly are the five PERMA elements weighted or combined into an overall judgment of flourishing?
Seligman insists the elements are independent and each pursued for its own sake, which deliberately avoids a single summary metric—but this leaves unresolved how to compare lives high in some elements and low in others, or how policy should trade them off.
Does teaching well-being produce durable, long-term flourishing rather than short-term gains?
The exercises and school/army programs show effects, but the book cannot fully establish whether increases in well-being persist over decades or fade, an admitted limit of the still-young intervention research.
Is the optimism–health link causal, and through what mechanism?
Seligman claims measurable biological impact, but correlational and observational data cannot fully rule out confounds (e.g., healthier people are more optimistic), and the mediating pathways remain speculative.
Can institutional well-being programs be applied without coercion or cultural imposition?
Applying PERMA to an entire army or school system raises consent and value-pluralism questions the book does not resolve—whose definition of flourishing gets institutionalized?
Where it falls short — a fair critique
The book asserts that the five PERMA elements are exhaustive of what people choose for their own sake, but offers no rigorous derivation or empirical test that these five (and no others—e.g., autonomy, security, justice) constitute the complete set. The theory is presented more as a considered proposal than as a validated taxonomy.
Seligman critiques Authentic Happiness for over-relying on a subjective 'feeling' metric, yet several PERMA components (positive emotion, meaning, even engagement) are still measured largely through self-report, so the shift may reproduce the very subjectivity problem it claims to escape rather than fully solving it.
The strong claims about optimism protecting against mortality and disease lean on associational epidemiology; presenting these as demonstrated causal 'biological impact' overstates what the cited evidence can support, given the difficulty of establishing causation in health-psychology data.
The public-policy vision of a national well-being dashboard largely brackets the political economy and measurement-gaming problems that plague any government metric—how indicators get manipulated, who controls them, and how competing conceptions of the good life are adjudicated in a pluralistic society.
Before you apply it
Using it well
Where the method fits, who it’s for, and the honest case for and against — so you apply it where it works.
Is this book for you?
For you if
- You want a structured model of flourishing, not just happiness
- You lead an institution and want to apply well-being at scale
- You value measurable, exercise-based self-improvement
Skip it if
- You need treatment for serious mental illness first
- You distrust framework acronyms over lived nuance
- You want deep philosophical debate on what 'the good life' means
Need first
- Baseline stability such that building well-being is feasible
- Openness to doing the recommended exercises consistently
- Willingness to accept measurement of subjective states
When it applies — and when it doesn’t
- An individual wanting to build a more fulfilling life beyond just chasing pleasure — PERMA offers a concrete, multi-dimensional framework to cultivate
- School leaders designing well-being curricula alongside academics — Positive Education has demonstrated real-world classroom applications
- Policymakers seeking well-being metrics beyond GDP — national well-being dashboards give measurable flourishing indicators
- Someone in active clinical depression or crisis seeking primary treatment — positive psychology supplements but does not replace clinical care
- Building resilience programs at institutional scale like the military — large rollouts preceded rigorous long-term outcome evidence
- Cultures where meaning and relationships are defined very differently — PERMA elements reflect largely Western framing of the good life
- Seeking a strictly evidence-settled, replicated science — many exercises predate the replication scrutiny era
- Using optimism claims to imply people cause their own illness — correlational health data can slide into victim-blaming
The honest case
Strongest case for
- PERMA captures distinct things people pursue for their own sake, unlike a single happiness metric
- Flourishing being measurable enables systematic, evidence-based intervention
- Real-world applications in schools and the army show scalability beyond theory
- Linking psychological states to biological health outcomes broadens the stakes
Strongest objection
- PERMA's five elements may be arbitrary or overlapping rather than exhaustive
- Self-reported flourishing measures are hard to validate objectively
- Health and large-scale claims outran the strength of the replicated evidence
- The model universalizes a culturally specific vision of a good life

Well-being and resilience skills can be systematically taught in schools, acting as a potent antidote to the high prevalence of youth depression.
Provides core evidence for the book's claim that well-being skills are teachable and can have lasting positive effects, forming a key part of the argument for Positive Education.
Referenced as a meta-analysis by S. M. Brunwasser and J. E. Gillham (2008) and specific studies like Gillham et al. (1995).
The causal link between positive emotional style and resistance to infectious illness.
Sheldon Cohen's Common Cold Studies
People with a high positive emotional style developed significantly fewer colds than those with an average or low positive style. The effect was bidirectional: positive emotion protected, and low positive emotion weakened. The effect was driven by positive emotion, not the absence of negative emotion.
Positive emotion has a direct, causal, and biologically-mediated protective effect on physical health, supporting the concept of 'Positive Health'.
Crucially supports the 'Positive Health' chapter by demonstrating with a rigorous experiment that a positive psychological state can causally improve physical health outcomes.
Cites studies by Sheldon Cohen and colleagues, such as Cohen et al. (2003) in Psychosomatic Medicine.

Hypothesis
Teaching resilience skills to soldiers via their sergeants will reduce rates of PTSD, anxiety, and depression, while increasing performance and rates of post-traumatic growth.
A 'wait-list control' design. A large group of soldiers (at least 7,500) will be taught the Master Resilience Training (MRT) materials by their trained sergeants. Their outcomes will be compared to a control group of soldiers who have not yet had the training.
Rates of PTSD diagnoses, performance records, physical health records, family life indicators, and measures of post-traumatic growth.
The group receiving resilience training will show better military performance, lower rates of PTSD and other mental illnesses, better physical health, and more post-traumatic growth compared to the control group.

- Man's Search for Meaning · Viktor Frankl
The book is referenced as a foundational work supporting the idea that human beings ineluctably want meaning and purpose in life, which is a core element (M) of Seligman's PERMA model.
- Human Accomplishment · Charles Murray
This book is cited for its analysis of how genius and extraordinary achievement are distributed, supporting the idea that a few individuals produce a disproportionate amount of output, which underpins the importance of extreme traits like GRIT.
- The Selfish Gene · Richard Dawkins
Used as a point of contrast to the theory of group selection. Seligman argues that the 'selfish gene' theory, focusing solely on individual selection, is insufficient to explain altruism and the importance of positive relationships.
- Lincoln's Melancholy · Joshua Wolf Shenk
Cited as a key example of how a person can function at an extremely high level and achieve greatness despite suffering from severe depression, illustrating the concept of 'dealing with it'.

How to measure it
Turning each idea into a measure
For each construct: how to operationalize it, the observable signals to look for, and how well it holds up.
An individual's rank-ordered profile on the 24 strengths as measured by the Values in Action (VIA) Signature Strengths survey.
- Demonstrating kindness to strangers
- Persisting on a difficult task
- Expressing gratitude to others
- Using humor to defuse a tense situation
The primary instrument is the VIA survey, which is a self-report questionnaire.
Score on the GRIT Scale, a self-report questionnaire developed by Angela Duckworth that assesses consistency of interest and perseverance of effort.
- Continuing to practice a skill for years despite setbacks
- Maintaining focus on a single long-term project rather than switching frequently
- Deliberate practice over thousands of hours
Measured via self-report scales.
Predicts success in challenging environments like West Point and the National Spelling Bee, above and beyond talent (IQ).
Measured through self-report scales of happiness, positive affect schedules (e.g., PANAS), and global life satisfaction questions.
- Smiling, laughing
- Verbal expressions of happiness or contentment
- Upbeat and energetic demeanor
Considered a purely subjective measure; if a person feels happy, they are.
Measured through self-report questionnaires about the frequency of flow experiences or through experience sampling methods (ESM) that ping individuals during daily activities to ask about their level of absorption.
- Losing track of time while working on a task
- Being unaware of surroundings while engaged in an activity
- Feeling that a challenging task feels effortless
Often assessed retrospectively, as one is typically not conscious of thought or emotion during the state of flow itself.
Measured via self-report scales of social support, perceived loneliness, and relationship satisfaction, as well as objective indicators like frequency of social contact or number of close friends.
- Spending quality time with friends and family
- Engaging in active-constructive responding to others' good news
- Having someone to call in a crisis
Has both subjective and objective components.
Measured via self-report scales on purpose in life and meaning, as well as behavioral indicators like hours spent volunteering or involvement in community, political, or religious organizations.
- Participation in community or religious groups
- Volunteering time for a cause
- Articulating a clear life purpose
Has both subjective (a feeling of purpose) and objective (actual service/belonging) components.
Measured via self-report on goal attainment and ambition, as well as objective metrics of achievement such as ranks, awards, promotions, or performance statistics in a given domain.
- Winning a competition
- Achieving a difficult personal goal
- Receiving a promotion or award
- Accumulating wealth for the sake of 'winning'
Has both subjective (pride) and objective (the win itself) components.
Measured through self-report scales assessing coping styles and optimistic explanatory style. It is also inferred from outcomes, such as the absence of PTSD or depression following a traumatic event, and a quick return to normal functioning.
- Maintaining performance under pressure
- Rapid recovery from setbacks
- Absence of clinical symptoms after trauma
- Challenging catastrophic thoughts
A central construct in the Penn Resiliency Program and the Army's Comprehensive Soldier Fitness program.
A composite measure based on assessments of the five PERMA elements. The book cites the Huppert & So (2009) operationalization, which requires an individual to have all 'core features' (e.g., positive emotions) and at least three of six 'additional features' (e.g., positive relationships, self-esteem, optimism).
- High productivity at work
- Strong and stable social networks
- Good physical health
- High levels of life satisfaction and happiness
Intended to be measured at the individual, organizational, and national levels.
A composite measure including subjective reports of vitality and energy, objective biological markers (e.g., high heart rate variability, low levels of inflammatory proteins like IL-6), and functional capabilities (e.g., ability to exercise vigorously, good sleep quality).
- Lower rates of cardiovascular disease
- Fewer infectious illnesses (e.g., common cold)
- Longer lifespan (lower all-cause mortality)
- Lower healthcare expenditures
Proposed as a new, empirical field of study that goes beyond the traditional risk-factor model of medicine.
