Psychological Richness Part 1 – Defining the Good Life: Happiness, Meaning, and Richness

Introduction

I’d like you to consider a deceptively simple question: what makes a life good?

This isn’t a new question. Plato warned that an unexamined life wasn’t worth living. Aristotle proposed that the good life was one of virtue and purpose. The Epicureans, by contrast, believed happiness came from pleasure and the absence of pain. Two thousand years later, we’re still having the same argument—only now with more data and better coffee.

The Old Debate: Happiness vs. Meaning

Modern psychology calls these two models hedonia and eudaemonia. A hedonic life is one filled with comfort, pleasure, and joy—the feeling of a good meal, a warm home, or laughter with friends.

A eudaemonic life is about purpose—serving something larger than yourself, having coherence, and feeling that your existence matters.

Bottom line up front: both matter, and neither is the complete answer. Each taken to extremes becomes hollow.

• Too much pleasure without purpose slides into shallowness.
• Too much meaning without joy can harden into martyrdom.

As positive psychology has grown into a legitimate body of scientific inquiry, these two dimensions have dominated the conversation about “the good life.” But not everyone’s fulfillment fits neatly into these categories. Some people live lives that are complicated, full of change, and still profoundly good. What new dimension might they be expressing?

The Third Dimension: Psychological Richness

Enter psychologist Shigehiro Oishi, who, along with colleagues, proposed a third dimension of a good life: a psychologically rich life.

He defines it as “a life characterized by a variety of interesting and perspective-changing experiences.”
Oishi writes, “Our lives are not zero-sum games where we must choose a single path to a good life.”

Richness doesn’t compete with happiness or meaning—it complements them. It’s not about chasing constant novelty or thrill-seeking. It’s about allowing life’s variety—its complexity and contradictions—to change how you see yourself and the world.

Where happiness soothes and meaning guides, richness stretches.

And that stretch begins with two key character strengths: humility and curiosity.

Humility says, “I don’t know it all.”
Curiosity says, “I want to find out.”

Without humility, we get rigidity and arrogance. Without curiosity, we stagnate. Together, they push us toward experiences that deepen us.

Creativity as the Function of Richness

If happiness is how we feel and meaning is why we act, richness might best be described as how we grow.

Martin Seligman and Gabriella Rosen Kellerman, in their book Tomorrowmind, explore what it takes to thrive in a rapidly changing world—particularly at work. Their PRISM framework outlines five critical capacities: Prospection, Resilience, Innovation, Social Connection, and Mattering.

They write, “We are all creatives now. In our own ways, from our own functional seats.”

They encourage us to pursue novelty, embrace ambiguity, and tolerate uncertainty—all in the service of creativity. Though they never mention Oishi, the parallels are clear.

Psychological richness provides the experiential fuel that drives creativity. Novelty generates the raw material; reflection turns it into insight.

In that sense, creativity is what psychological richness does when it’s working right.

Richness and Resilience in Practice

Richness doesn’t mean easy. Bad events remain bad—war, loss, illness—but they can still expand perspective when processed well. It’s the difference between being broken by hardship and being reshaped by it.

I’ve often joked that my guilty pleasure for romantic comedies and terrible reality TV has turned out to be surprisingly educational. The rom‑coms—yes, even the formulaic ones—usually have more to say about growth than most self‑help books. And the trashier end of reality television? It’s a fascinating laboratory for watching positive psychology concepts go wonderfully, and sometimes catastrophically, off the rails.

Take Netflix’s The Life List, for instance. The protagonist inherits a challenge from her late mother: complete the dreams she listed as an adolescent. Each task forces her to take risks, encounter new people, and see herself differently. The journey is awkward, uncomfortable, and at times painful—but by design. The intended effect is growth through perspective shifts. The movie is a charming illustration of psychological richness as an engine for self‑development and resilience.

On the other end of the spectrum—and this is where my sweet tooth for bad TV kicks in—consider Too Hot to Handle, where contestants are lured onto the show by their appetite for novelty and superficial pleasure. The show only becomes interesting when participants are forced to reflect—to connect their choices to something meaningful. It’s an accidental case study in Oishi’s theory: unprocessed novelty isn’t richness, it’s distraction. Only when reflection enters the picture does it have the potential to drive growth.

Quick Summary of Oishi’s Model: A Psychologically Rich Life

• Core Definition: A life marked by variety, novelty, and perspective-changing experiences.
• Purpose: Complements happiness (comfort) and meaning (purpose) by emphasizing growth through complexity.
• Emotional Range: Includes both positive and negative experiences that lead to reflection and learning.
• Drivers: Humility (admitting limits) and curiosity (seeking to expand them).
• Processing Requirement: Reflection, journaling, and storytelling convert novelty into depth.
• Outcome: Greater wisdom, openness, and adaptability across cultures and life stages.

The Three Pillars of a Good Life

Hedonia	Eudaemonia	Richness
Comfort, pleasure, joy	Purpose, meaning, coherence	Variety, novelty, perspective shift
“I had fun.”	“I made a difference.”	“What a journey.”

Psychological richness fills a gap left by eudaemonia and hedonism. Whether you think richness is an end in itself or a means to the other aspects of a good life, the distinction may not matter—these three dimensions are integral pillars of a life worth living.

Each pillar strengthens the others. Happiness without meaning becomes empty. Meaning without happiness becomes brittle. Richness without the other two becomes chaos.

A balanced life doesn’t reject any of them—it learns when to seek each and when one can be used to access the others.
Bored and lacking joy? Try something new that also carries meaning. Feeling like an unappreciated martyr? Seek novelty that also brings delight. These are not mutually exclusive notions of the good life—they are complementary dimensions of one.

Conclusion…

In the next installment, we’ll dig deeper: what happens when the model itself starts to wobble? What biases and blind spots does psychological richness have? How does this theory mesh with other foundational positive psychology models? And what impact do our current moral, ethical, and intellectual frameworks have on how these ideas are put into practice?
