The Algebra of Happiness

The Algebra of Happiness Plot Summary

Introduction

On a crisp autumn evening, I found myself sitting across from an old professor in a quiet café. His eyes sparkled with wisdom as he drew equations on a napkin—not mathematical formulas, but what he called "the algebra of happiness." These weren't calculations of money or status, but the variables and constants that truly define a life well-lived. The moment stayed with me, reminding me that our most profound questions often have answers that are both simpler and more complex than we imagine. This book takes us on a journey through life's most important equations—the ones that determine our success, relationships, and ultimately, our happiness. Through candid personal stories and hard-earned wisdom, we discover that happiness isn't about perfection or extraordinary achievement. Rather, it emerges from understanding key patterns: how career choices shape our identity, how relationships sustain us through life's storms, and how our daily habits gradually become our destiny. The author doesn't offer abstract theories but shares raw, sometimes uncomfortable truths about work, love, family, and the passage of time—all delivered with a refreshing blend of humor and unflinching honesty.

Chapter 1: The Basics: Equations of a Life Well-Lived

At age thirty-four, I was convinced I had life figured out. A successful tech company, a fashionable San Francisco address, and enough disposable income to consider buying a private jet—not just renting one. During the dot-com boom, I joined other young tech founders browsing Gulfstreams at an airfield outside the city. The absurdity didn't register: thirty-something guys with one-bedroom apartments considering purchasing flying homes that cost the equivalent of a thousand years of my mother's salary as a secretary. When the inevitable crash came, it hit hard. Reality has a way of humbling us. The market collapsed, my paper wealth evaporated, and suddenly that private jet viewing seemed like a fever dream. Looking back now, I recognize this as a fundamental equation of life: success and failure aren't permanent states but points on a curved line that inevitably changes direction. Between our twenties and mid-forties, life gets real. The stress of building the life we've been told we deserve takes a toll. We realize that despite what our teachers and parents told us, we likely won't become senators or have fragrances named after us. Then something happens—someone we love gets sick and dies, and the harshness of life comes into full view. But there's another part to this equation. In our fifties (earlier if we're fortunate), we begin to register all the wonderful blessings that surround us. Beautiful beings that look and smell like us—our children. The ability to deliver some sort of skill or intelligence that people will pay us for, enabling us to support our families. The opportunity to travel across the world and witness amazing things extraordinary people have built. When tragedy strikes, it's often beaten back by our best ideas: science and human connection. As we recognize our time is limited, we start smelling the roses and finally afford ourselves the happiness we deserve. The most important decision you'll make isn't where you work or who you party with, but who you choose as your life partner. Having a spouse who you not only care for and want to have sex with, but who's also a good teammate, softens life's rough edges and magnifies its brightness. Good partners align on three things: physical attraction, shared values (religion, children, money, family), and complementary approaches to life's challenges. Money matters especially—the number one source of marital discord is financial stress. Perhaps the most reliable equation for happiness balances ambition with appreciation. We need to work hard, especially when young, to create economic security. But simultaneously, we must take notes on what truly brings us joy and invest in those things. Pay special attention to activities that bring happiness without mind-altering substances or excessive spending. Whether it's cooking, playing guitar, or mountain biking, finding your "zone" where you lose track of time creates authentic happiness that no career achievement can match.

Chapter 2: Success: Finding Your Path in a Competitive World

When I was around five, I noticed people behaved differently around my father. They gazed into his eyes, nodding and then laughing. Women would touch his arm while laughing, and men would yell, "Tommy!" genuinely happy to see him. My mother explained it simply: "Your father is charming." At gatherings, a semicircle would form around my dad as he told jokes and shared his take on things from space exploration to management principles. This charm sustained an upper-middle-class lifestyle for our family as he roamed the western United States selling fertilizer for O.M. Scotts & Sons. In his late fifties, after being laid off, my father began giving seminars at a local community college. The setting was unimpressive—cheap fluorescent lighting, folding chairs, an overhead projector with smudged transparencies, and a table with half-empty soda bottles and lemon squares my stepmom had baked. About fifteen people would attend, most in their fifties and sixties. As a teenager, I found these seminars depressing. In exchange for sharing his wisdom with other mostly unemployed people, my dad paid for gas and treats. Yet he reflects on these seminars as the happiest time of his life. He was where he meant to be—in front of people, speaking and teaching. I didn't inherit my father's charm. In fact, being offensive—the opposite of charm—became my specialty. Not a "speak truth to power" kind of offensive, but a tone-deaf "saying exactly the wrong thing at the exact wrong moment" kind. However, my father did pass on the ability to hold a room. One-on-one, I'm an introvert, insecure even. But as the room fills, different skills emerge. In front of dozens, crisp insights find me. In front of hundreds, humor and warmth appear. With thousands, I feel a rush of adrenaline and confidence to be inspiring. To hone this craft, I teach every Tuesday night for three hours in front of 170 second-year MBAs. I make much less than at corporate speaking events—about $1,000 per podium hour. The investment to reach this platform—advanced degrees, department politics—is substantial. Yet my father, at eighty-eight, will only get on a plane for two things: to see the Toronto Maple Leafs play or to watch his son teach. He sits in the back row of my classroom. When visitors introduce themselves, he waits until they're done and says, "I'm Tom Galloway, Scott's father." There's a pause, then sustained applause. The difference between bribing people to listen with lemon squares and being paid $2,000 per minute isn't talent—my dad has more. The difference is being born in America and benefiting from California taxpayers, who gave a secretary's child the chance to attend a world-class university. Success combines talent with opportunity, education, and timing. The wind of our society's current obsession with technology blows at my back, amplifying my voice on topics that happen to be in demand. My market value, like all things, will fade. People will tire of my subject matter, or my creative juices will stop flowing. Understanding this temporary nature of success creates both urgency and humility—the true algebra of sustainable achievement is knowing your worth while recognizing the factors beyond your control that contribute to it.

Chapter 3: Work Ethic: How Hunger Drives Achievement

I think a lot about success and its underpinnings. Talent is key, but it will only gain you entrance to a crowded VIP room. Kind of like Platinum Medallion on Delta: you think you're special, but at LaGuardia, you realize there are a lot of you. Let's assume you are exceptionally talented. Maybe even in the top 1 percent. Congrats: you join 75 million people, the population of Germany, all vying for more than their share of the world's resources. Most young people aspire to be in the top 0.1 percent, and talent alone won't get you within spitting distance. The chaser that takes talent over the top into success is hunger. Hunger can come from many places. I don't think I was born with it. I have a great deal of insecurity and fear, which, coupled with natural instincts, has resulted in hunger. For the first eighteen years of my life, I didn't work hard. At UCLA, we all started as nice, smart, attractive people who had crushes on each other based on a clumsy sense of attraction. But by senior year, the women were gravitating toward guys who had their shit together, showed early signs of success, or already had the trappings of success thanks to rich parents. My instincts kicked in—I wanted to increase my selection set of potential mates. I decided this required signaling success, so I landed a job at Morgan Stanley despite having no idea what investment bankers did. It didn't take long to realize that pursuing success without fulfillment leads down a road of misery. The second transformative event involved my mother's diagnosis with aggressive breast cancer. When I visited her, I found her lying on the couch, contorted and vomiting into a trash can. She looked at me and asked, "What are we going to do?" We were underinsured, without medical connections. I wished desperately for more money and influence, knowing they would bring access to better healthcare. In 2008, when my girlfriend got pregnant, instinct kicked in again. The financial crisis hit me hard, going from somewhat wealthy to definitely not. During the previous crisis in 2000, the impact had rolled right off me—I was in my early thirties with only myself to worry about. But now, not being able to provide for my son at the level I envisioned seriously challenged my sense of purpose and worth as a man. The pressure many of us put on ourselves to be good providers is often irrational, but the instinct to protect and nurture offspring is core to our species' success. Understanding hunger requires examining its sources—insecurity, desire for status, parental instinct—and channeling it productively. The true equation of achievement balances hunger with self-awareness. Hunger without reflection leads to empty success; reflection without hunger leads to unfulfilled potential. Finding your own unique combination of both is the key to meaningful accomplishment. As I've gotten older, I've noticed my hunger changing complexion. It's becoming more a pursuit of relevance than money. I'm spending more time with people and projects I care about, sometimes at the expense of economic opportunities. I'm trying to instill a sense of hunger in my boys through chores and connecting work with reward. Sometimes I even mug them (tackle them and steal their money) on the way to their room after paying them. That, too, is a life lesson.

Chapter 4: Relationships: The Foundation of Genuine Happiness

I've been thinking about AIDS a lot lately. I hope we never see an epidemic this devastating again. One million people died from AIDS-related causes in 2017, and 36 million have succumbed to the disease since the beginning of the epidemic. In sum, the HIV virus has killed the equivalent of the population of Canada. In 1985, I remember sitting in the dining room of my fraternity and reading an L.A. Times article about scientists making progress toward an HIV vaccine. That meant this abstract thing called AIDS, that none of us had any contact with, was over. Only it wasn't, and all of us would know several people who'd contract HIV and ultimately die from an AIDS-related illness. We took cold comfort believing AIDS was a disease only gay men got. And none of us knew anybody who was gay. But we did. A bunch of us were gay. Only most, if not all, of the heterosexuals in our circle had no idea. You couldn't be openly gay at UCLA in the eighties. It didn't matter how brave or comfortable with yourself you were. Being gay was unnatural. We were young men and women at UCLA, which was a postcard for natural and wholesome, and there was no tolerance for challenging that image. Years later, after moving to San Francisco, my then-wife and I would see ghosts everywhere in the Castro district—men in their thirties and forties who were painfully thin with sores littering their bodies. Thirty-five-year-old men who looked eighty, barreling toward death. Some of our friends from UCLA who contracted HIV: Bill Aarons, a quiet, handsome fraternity brother we later discovered was a hemophiliac; Ron Baham, a preppy black kid with a movie star voice; Pat Williams, my UCLA freshman roommate who grew up on a farm and came to study theater; Tom Bailey, my best friend Jim's partner, a creative director at an ad agency. Bill was the first to die, having contracted the virus from clotting factors made from donated blood. Ron became a talent agent and rose to director of current TV at Disney by thirty, before taking his own life at thirty-three. Pat faded away, struggling with his sexuality and attending "reeducation" camps. I'm ashamed I didn't track him down before he died. Tom, thankfully, was caught by modern medicine and has been on antiretroviral treatment for twenty years. He's the godfather to my oldest son. The AIDS crisis teaches us profound lessons about connection and acceptance. College was for "fast thinking"—where homosexuals were "fags" and "gay" was a slur. The decade after was for "slow thinking"—discovering people we loved were gay, with similar hopes and problems, only stalked by a plague. Our initial response as a nation will remain a stain on the American story. But the crisis also revealed the extraordinary power of authentic relationships—how they sustain us through the most unimaginable circumstances and form the foundation of our humanity. Through the lens of this epidemic, we see a fundamental truth: deep connections with others, free from judgment and conditional acceptance, are what make life meaningful. The real measure of our humanity isn't how we treat those who conform to our expectations, but how we respond to those who challenge our understanding. True relationships require vulnerability, compassion, and the courage to confront our own prejudices.

Chapter 5: Love: Unconditional Giving as Life's Ultimate Purpose

Love and relationships are the ends—everything else is just the means. We, as a species, segment love. When we are young, we take in love—our parents', teachers', caregivers'. When we enter adulthood, we find transactional love; we love others in exchange for something in return—their love, security, or intimacy. Then there's complete love, surrendering to loving someone regardless of whether they love you back, or whether you get anything in return. No conditions, no exchange, just a decision to love this person and focus solely on their well-being. Love received is comforting, love reciprocated is rewarding, and love given completely is eternal. You are immortal. Our role, our job as agents of the species, is to love someone unconditionally. It's the secret sauce cementing the survival of Homo sapiens. And to ensure we continue to enlist in this act, nature made it the most rewarding. To love someone completely is the ultimate accomplishment. It tells the universe you matter, you are an agent of survival, evolution, and life. When my oldest son was two, he'd wake up at dawn, gather his most precious possessions (Matchbox cars), put them in a wicker basket, and head to our room. He would stand at the door and extend the basket, a nonverbal offering in exchange for letting him into bed with us. We would refuse and take him back to his bed. This cycle would repeat every fifteen minutes until we all got up. Several mornings we found him asleep just outside our door, wanting to come in but too afraid of being rejected. There are few things about parenting I regret more than turning away our oldest from joining us in sleep. Our intentions were good. Western research on co-sleeping emphasizes the importance of kids developing coping systems and confidence from sleeping on their own. But there's no one-size-fits-all approach, and most cultures lean toward a pack approach to sleep. I counsel new parents to do what feels right for them and trust their instincts. Our instinct now is to ensure everyone starts in their own bed but see how things play out during the night. Some nights everyone wakes up where they started; most nights there are three or four in our bed. The Japanese refer to co-sleeping as "the river": mom and dad as the banks, the child in between as the water. The waters in our bed are serene rivers that storm unexpectedly, delivering kicks to the face and errant questions. My youngest is most comfortable sleeping perpendicular across my throat like a 35-pound bow tie. My oldest likes to have one foot touching his mom or dad at all times, sitting up every ninety minutes to look around the room before going back to sleep. I'm banking on these small investments made several times a week in the middle of the night paying dividends. Less space in bed, errant bruises, and generally less sleep are deposits compounding toward one goal: that they will remember their parents chose them over everything else. We come into and leave this world alone and vulnerable, wanting the touch of people we know love us so we can sleep in peace. The equation of love is both simple and profound—what we give freely returns to us in ways we could never calculate.

Chapter 6: Health: Maintaining Balance in Body and Mind

As Dr. Henry S. Lodge says, we are hunter-gatherers and are happiest when in motion and surrounded by others. A decent proxy for your success will be your ratio of sweating to watching others sweat (watching sports on TV). It's not about being ripped, but committing to being strong physically and mentally. The trait most common among CEOs is that they exercise regularly. Walking into any conference room and believing that, if things got real, you could outperform the others gives you an edge and confidence. My height and weight are a major focus for me, as I was painfully skinny growing up. When I arrived at UCLA, I was 6 foot 3, 138 pounds. Joining the crew team and having access to three meals a day resulted in thirty new pounds of muscle. Soon after the weight gain, women started noticing me—which was awesome. Since then, I've associated strength and muscle with worth as a mate. I'm losing muscle strength now and haven't found other sources of security and worth. I'm struggling with this whole aging thing. I'm increasingly aware of my mood, heartbeat, and blood pressure as I get older. Recently at the Founders Forum in London, I discovered I wasn't speaking at a plenary session but at one of two concurrent sessions. My inner jackal voice immediately registered this as a grave injustice. The event was impressive, but I arrived feeling faint from not eating. I wolfed down two lattes and an apple seven minutes before going onstage, where I proceeded to yell at the audience for thirty minutes through 143 slides. About twenty minutes in, there was feedback on the sound system, and I began having irregular heartbeats. I tried calming myself by thinking: if I collapsed onstage, I'd get a ton of views on YouTube. As I've gotten older, I've experienced more anxiety during public speaking. About 1% of my 400 talks over five years have come off the rails—I become anxious, start sweating, my voice shakes, and I feel like passing out. At DLD15 in Munich, I nearly collapsed onstage and had to lean over with my hands on my knees for thirty seconds. The organizers wanted to take me to the hospital, convinced I was having a cardiac event. Yet the talk received 1.1 million YouTube views, with few viewers noticing my distress—another reminder that nothing is ever as good or bad as it seems in the moment. I've started registering the individuality of emotions more clearly too. Crying may have evolutionary purposes—signaling surrender, eliciting empathy, helping parents locate offspring. Men aren't supposed to cry, which likely relates to the "indicates surrender" aspect. The first time I remember really crying was at age nine after my parents separated. Watching The Partridge Family with my dad, I suddenly began sobbing uncontrollably for thirty minutes. I lost the capacity to cry between ages thirty-four and forty-four—didn't cry during my divorce or when my mom died. But since my mid-forties, something strange has happened: I cry all the time. This emotional awareness represents a fundamental health equation: physical and mental well-being are inseparable. Our bodies house our minds, and our minds interpret our physical experiences. Finding balance means acknowledging both aspects of health—strengthening our bodies while allowing our emotions full expression. The most sustainable approach to health isn't perfection in either realm, but integration of both into a complete picture of wellness that evolves as we age.

Chapter 7: Aging: Gaining Perspective Through Time

My family—my dad, sister, and I—are not close by American standards. No BBQs, daily calls, or watching sports together. However, I'll trade closeness for harmony, and we have plenty of that. My friends with uber-close but dysfunctional family relationships are often exhausted for the wrong reasons. The three of us are low maintenance, no-drama, and additive to each other's lives. An unexpected bonus is, in addition to loving each other, we like each other—we get along well. Every few years for the last two decades, we've gone to Cabo, which my dad loves. This time, however, was harder. My dad is eighty-eight and has lost a lot of weight recently. His leg muscles have atrophied, and he's having trouble walking. Our dad had been "that guy" who never seemed to age, so him requiring assistance is rattling. Some of his most treasured items are medals for placing first in his age group (fifties) in several 10K races. He's especially fond of one photo showing him on the medals podium celebrating his victory with a cigarette. Both my sister and I have worked out three-plus times a week since we were eighteen. Our chain-smoking, 10K-medalist father got us exercising in our teens, and it stuck. We will all need help walking at some point, but that day will likely come years later for my sister and me than for most people, thanks to him. The highlight of each trip is the three of us beachside drinking our dinner. The conversation inevitably turns to my dad's ex-wives (three of them), my sister's ex-boyfriends, and my neuroses. None of these topics are that interesting, but with several margaritas they become hilarious. Caregivers live longer than any other group, and the number of people you love and care for is the strongest signal about how long you'll live. Like many men, I haven't provided much care for many people. I spend time with my kids, but their mom is their primary caregiver. Getting my dad to and from Cabo and around a hotel is the most real caregiving I've done since my mom was sick. You can feel the benefits. It's taxing but rewarding. You have to be engaged and organized (key to brain health), and you feel you have purpose. I told my dad it was time to start getting wheelchair service at airports, and he was cool, even Zen, about it. Being wheeled through security, he seemed relieved not to have to think about all the hassles on the other side of the metal detector. In front of us was someone else in a wheeled vehicle, a two-year-old girl who was screaming, clearly not convinced the wheels were a function of people caring about her. My dad, however, knows this is true. The fastest-growing demographic is centenarians. How can you live to be one hundred? Have good genetics, live a healthy lifestyle, and love others. Loving is the bomb when it comes to living. We like to think genetics are number one, so we can abdicate responsibility for abusing our bodies. But that's not true. As we age and encounter more x-factor moments—like people dying when they shouldn't—we adjust our priorities. We start wondering, "Why am I so stressed today, trying to build a better tomorrow, when I'm equally stressed the next day? When does tomorrow, the reward, become today?"

Summary

The algebra of happiness isn't about complex formulas but recognizing fundamental patterns. Success isn't determined by raw talent alone but by hunger—that internal drive fueled by insecurity, desire for connection, or responsibility toward others. The equation balances professional achievement with personal fulfillment, recognizing that career trajectories matter less than who you share your life with and how you care for them. The most powerful variables in this equation are the relationships we build—not just romantic partnerships, but the full spectrum of human connections that give our lives meaning. Through stories of triumph and heartbreak, we discover that happiness emerges from seemingly contradictory forces: ambition paired with acceptance, independence alongside interdependence, and the courage to pursue success while acknowledging our limitations. The most profound equation teaches us that unconditional love—giving without expectation of return—creates the highest form of fulfillment. Whether caring for children, aging parents, or communities in need, we find purpose in service to others. Our legacy isn't measured by wealth accumulated but by love distributed, not by achievements celebrated but by relationships nurtured through life's inevitable ups and downs. The algebra of happiness ultimately reveals that what we give freely is what endures beyond our time—the only true form of immortality available to us.
