“The How of Happiness” by Sonja Lyubomirsky (Book Summary)

NOTE: If you're into the science of happiness and positive emotions, check out our latest book, The Happy Life Formula. It's all about creating more happiness in our lives so that we can become not only happier, but also healthier and more successful.


The How of Happiness by Sonja Lyubomirsky is the most complete book on the science of happiness and wellbeing I’ve ever read.

Its premise is simple: We all want to be happier, but few of us know how to go about improving our happiness.

Well, this book changes that. Using sound scientific research, it shows you exactly how to go about raising your levels of happiness.

The book essentially does three things: 1) It explains how happiness works. 2) It explains why happiness matters. 3) It outlines 12 science-backed activities for becoming happier.

If you’re new to Positive Psychology—the science of well-being and flourishing—this book is where to start.

Who is The How of Happiness for?

  • Anyone interested in becoming happier.
  • Anyone interested in a scientific approach to happiness and flourishing.
  • Anyone looking to improve their life.

1. We All Want Happiness… But We’re Looking in the Wrong Places

“In almost every nation—from the United States, Greece and Slovenia to South Korea, Argentina and Bahrain—when asked what they want most in life, people put happiness at the top of their lists.”
“What do you think would make you happier? Take a moment to consider. Might it be:
  • A relationship?
  • More flexibility at work?
  • A new job that better provides for you and your family?
  • An extra bedroom?
  • A more attentive spouse?
  • A baby?
  • Looking younger?
  • Relief from your bad back?
  • Losing weight?
  • Your child excelling at school?
  • Knowing what you really want to do with your life?
  • More supportive, loving parents?
  • Cure from a chronic illness or disability?
  • More money?
  • More time?
If your answers look anything like these, all of which friends have confided to me over the years, you’re in for a surprise. None of these things will make you substantially happier. But this doesn’t mean that the goal of finding lasting happiness is unrealistic or naïve. The catch is that we tend to look for happiness in the wrong places. What we believe would make a huge difference in our lives actually—scientific research shows—makes only a small difference, while we overlook the true sources of personal happiness and well-being.”

That’s where most of us find ourselves: We want happiness… but we have no clue how happiness works.

Happiness is literally the number one goal for most people in life. It’s what we’re chasing all of our lives. Yet do we ever question whether our assumptions about happiness are correct? Do we ever stop and dare to figure out happiness really works?

That’s why Positive Psychology and the science of happiness is so important. It shows us what really makes us happy and what doesn’t. Knowing that, we can finally create our lives in ways that are optimized for happiness.

2. The Pie-Chart Theory of Happiness

“The result of our discussions over the next few years was a discovery about the causes of well-being. Together, we were essentially able to identify the most important factors determining happiness, represented in the following simple pie chart.”

So, the pie-chart theory shows us how happiness really works: Your level of happiness is determined by your genetic set-point (accounting for 50% of the variance in happiness), external circumstances (10%), and intentional activity (40%).

Let’s unpack those variables a bit:

  • Your genetic set-point (50%). Your genes determine 50% of your happiness. In other words, half of your level of happiness is fixed, hence the word set-point. You’re either lucky to have “happy genes” or unlucky to have “unhappy genes.” There’s nothing you can do about it.
  • External circumstances (10%). This is what shocks most people: Your life circumstances—whether you’re rich or poor, healthy or unhealthy, married or divorced, beautiful or plain, driving a new or an old car—only account for a measly 10% of your happiness. This explains why some kids in Brazilian slums can be just as happy as grumpy millionaires in the Western world. “Stuff” and other circumstances just don’t have much of an impact on happiness.
  • Intentional activity (40%). This refers to our behavior: what we do and how we think. As far as boosting our happiness goes, this is where the money is. Why? Because it makes up a whopping 40% of our happiness. Plus our behavior is much easier to change than our circumstances.

So there you have it. That’s how happiness works.

There are two important takeaways here. First, happy people aren’t happy because they have more money, faster cars, or better looks than their less happy peers. Instead, where they differ is in their behavior: they engage in more behaviors that boost happiness, such as spending time with their family, practicing optimism, exercising regularly, savoring life’s pleasures, living in the present moment, or expressing gratitude for what they have.

Second, the key to happiness lies not in changing your genes (which is impossible) and not in changing your circumstances (which is hard and impractical), but in changing what you do and how you think.

3. Three Happiness Myths Holding You Back

“One of the great obstacles to attaining happiness is that most of our beliefs about what will make us happy are in fact erroneous. Yet they have been drummed into us, socialized by peers and families and role models and reinforced by the stories and images ever-present in our culture. Many of the presumed sources of happiness seem so intuitive and so commonsensical that all of us—even happiness researchers!—are prone to fall under their spell. This is where science can shine a clear and vivid light. The three major myths about happiness that we tend to fall for are plainly illuminated by the happiness pie chart.”

As I alluded to before, our false assumptions about happiness are keeping us from becoming the happiest we could be.

Sonja Lyubomirsky mentions the following three myths in the book:

  • Myth No. 1: Happiness must be found. Happiness isn’t something you find; it’s something you create for yourself. It’s something you practice, not something you search for. Happiness lies in changing your behavior, not getting to some magical place in the future where all your worries will subside. It’s attainable now, but it requires effort.
  • Myth No. 2: Happiness lies in changing our circumstances. This is the classic fallacy of “I will be happy when ______.” Again, research shows it doesn’t work that way. Changing your circumstances doesn’t matter, as far as happiness is concerned. If you want to feel happier, work on what you do and how you think.
  • Myth No. 3: You either have it or you don’t. Many people subscribe to this notion that we are born happy or unhappy, and there’s nothing we can do about it. As the pie-chart theory clearly shows, that’s not true. Yes, genes make a difference, but there’s still plenty you can do to overcome your genetic programming.

4. Why Do Circumstances Account for So Little?

“One of the great ironies or our quest to become happier is that so many of us focus on changing the circumstances of our lives in the misguided hope that those changes will deliver happiness. For example, in an attempt to allay unhappiness, a recent graduate may choose a high-paying job in a distant city, a middle-aged divorcee may undergo beautifying cosmetic surgery, or a retired couple may buy an apartment with a view. Unfortunately, all of these individuals will probably only become temporarily happier. An impressive body of research now shows that trying to be happy by changing our life situation ultimately will not work.
Why do life changes account for so little? Because of a very powerful force that psychologists call ‘hedonic adaptation’.”

Life circumstances are the stable facts about your life: your gender, age, ethnicity, where you grew up, and significant life events that shaped your childhood, adolescence, and adulthood. They also include your occupation, income, religious affiliations, living conditions, health status, and whether you’re married, divorced, widowed, separated, or single.

All of these circumstances put together only account for 10% of how happy people are.

How is that possible?

It’s possible because of a peculiar phenomenon called hedonic adaptation—“the observed tendency of humans to quickly return to a relatively stable level of happiness despite major positive or negative events or life changes.”

At first, we react strongly to changes in circumstances, but, over time, their emotional impacts lose their power. We take good things for granted. We overcome obstacles. In both cases, we may freak out in the beginning, but then move on as if it were no big deal. In other words, we adapt.

You’ve undoubtedly experienced this in your own life. The initial thrill of a new house, car, or pay raise is wonderful, but the enjoyment rarely lasts for more than a couple of days.

Winning the lottery is a good example. Research shows that within a few months, people who win the lottery are about as happy as they were initially.

So that’s the bad news about hedonic adaptation: Positive events and circumstances may feel good in the moment, but due to our natural propensity to adapt, they will never create lasting happiness.

And now for the good news: I propose that we’re actually lucky to have this ability to adapt quickly to changing circumstances. Why? Because it’s incredibly useful when bad things happen.

Without this ability, we would always be at the mercy of what happens in our lives. If something good happens, cool. If something bad happens—the death of a loved one, or the suffering of a debilitating injury—we’d be miserable for our lives.

Hedonic adaptation acts like a safety guard preventing us from spiraling into the abyss of depression after negative life events. Meanwhile, we can optimize our behavior (which accounts for 40% of our happiness!) and create happiness for ourselves that way. Bingo!

5. The Benefits of Happiness

“…becoming happier doesn’t just make you feel good. It turns out that happiness brings with it multiple fringe benefits. Compared to their less happy peers, happier people are more sociable and energetic, more charitable and cooperative, and better liked by others. Not surprisingly then, happier people are more likely to get married and to stay married, and to have a richer network of friends and social support… they actually show more flexibility and ingenuity in heir thinking and are more productive in their jobs. They are better leaders and negotiators and earn more money. They are more resilient in the face of hardship, have stronger immune systems and are physically healthier. Happy people even live longer.”

Happiness is more than a feel-good state. It’s a state of high performance, greater resiliency, thriving health, and boosted productivity.

Our minds and bodies literally perform at their best when we’re feeling good.

Entire books have been written on how we can capitalize on the performance-enhancing effects of happiness and use them to create more success for ourselves. Rather than the result of success, happiness seems to be the cause of it.

Check out our summaries of The Happiness Advantage and The Happiness Track for more on this.

6. Happiness Takes Effort

“It may be obvious that to achieve anything substantial in life—learn a profession, master a sport, raise a child—a good deal of effort is required. But many of us find it difficult to apply the notion of effort to our emotional or mental lives. Without effort, we might ‘get lucky,’ but like a long-forgotten New Year’s resolution, the success will be short-lived. Consider how much time and commitment many people devote to physical exercise, whether it’s going to the gym, jogging, kickboxing, or yoga. My research reveals that if you desire greater happiness, you need to go about it in a similar way. In other words, becoming lastingly happier demands making some permanent changes that require effort and commitment every day of your life. Pursuing happiness takes work, but consider that this ‘happiness work’ may be the most rewarding work you’ll ever do.”

Changing your behavior—especially lifelong habits!—takes effort.

Most happiness activities, as you’re about to see, aren’t exactly easy to follow through with. Applying these strategies in your life takes planning, effort, and dedication.

So, if you’re serious about becoming happier, pull up your sleeves, spit in your hands, and get ready to put in the work.

7. The 12 Happiness Activities

  • Expressing Gratitude
  • Cultivating Optimism
  • Avoiding Overthinking and Social Comparison
  • Practicing Acts of Kindness
  • Nurturing Social Relationships
  • Developing Strategies for Coping
  • Learning to Forgive
  • Increasing Flow Experiences
  • Savoring Life’s Joys
  • Committing to Your Goals
  • Practicing Religion and Spirituality
  • Taking Care of Your Body (Meditation, Physical Activity, Acting Like a Happy Person)

These are Sonja Lyubomirsky’s 12 science-backed happiness activities. The book explains why each activity works and then gives multiple ways to practice it.

We’ll now discuss three specific strategies.

8. Break the Habits of Overthinking and Rumination

“The evidence that overthinking is bad for you is now vast and overwhelming. If you are someone who is plagued by ruminations, you are unlikely to become happier before you can break that habit. Indeed, I will go so far as to say that if you are an overthinker, one of the secrets to your happiness is the ability to allay obsessive overthinking and to reinterpret and redirect your negative thoughts into more neutral or optimistic ones.”

If you’re struggling with overthinking, you need to find a way to fix it. Otherwise, as Lyubomirsky says, you might as well forget about happiness. And yes, you can fix this disease of overthinking! I’ve done so myself. Sure, I’m nowhere near perfect, but compared to when I was younger, I’m 100 times better.

So, how can you overcome rumination and overthinking? Two strategies from the book are:

  • Healthy distractions. Instead of letting one bad thought or event escalate into hours of rumination, redirect your full attention somewhere else—engage in physical exercise, read a captivating book, watch a funny video, or meet a friend. Anything that fully absorbs your attention will do the trick.
  • Writing it down. Putting your ruminations into words helps you organize them, make sense of them, and discover a pattern you weren’t aware of before. It helps you unburden yourself from the thoughts, allowing you to move past them.

But hands down the best strategy to break the deadlock of overthinking is mindfulness—the ability to step back from your thoughts/feelings and watch them from a safe distance in a nonjudgmental and accepting way.

Mindfulness is the most important skill I’ve ever come across in my entire life. Not only has it helped me beat the curse of overthinking, it has also made me a happier, kinder, more compassionate, more productive, and overall better person.

Let’s discuss this further in the next point.

9. Practice Mindfulness

“A series of studies conducted at the University of Rochester focused on people ‘high in mindfulness’, that is, those who are prone to be mindfully attentive to the here and now and keenly aware of their surroundings. It turns out that such individuals are models of flourishing mental health. Relative to the average person, they are more likely to be happy, optimistic, self-confident and satisfied with their lives, and less likely to be depressed, angry, anxious, hostile, self-conscious, impulsive or neurotic.
Furthermore, people who are habitually mindful of their current experiences are more likely to experience frequent and intense positive emotions, to feel self-sufficient, competent and to have positive social relationships, while those who are not usually mindful report more illness and physical symptoms.”

In short: mindfulness is great. So how do you practice it? There are two ways: formal and informal.

Formal practice is what we call meditation. You take time out of your day to focus on an object of concentration (e.g., your breath), and bring your mind back to that object every time you get distracted and are lost in thinking.

Informal practice doesn’t require taking any time out of your day. Instead, you simply do whatever you’re currently doing in a mindful way. We call this mindful eating, mindful cooking, mindful showering, or mindful commuting. Whatever you do, you give your full attention to it. When you get lost in thought, you bring your attention back to the task at hand. That’s easier said than done, but that’s the gist of it.

If you’re new to this, you want to start with formal practice so that you get a feel for what mindfulness involves and what it feels like. If you’re to take the plunge, check out our beginner’s guide on meditation and start a daily practice.

10. Have a Project

“In 1932, weighed down by the sorrows and agonies of his self-absorbed and aimless clients, an Australian psychiatrist named W. Béran Wolfe summed up his philosophy like this: ‘If you observe a really happy man you will find him building a boat, writing a symphony, educating his son, growing double dahlias in his garden, or looking for dinosaur eggs in the Gobi Desert.’ He was right. People who strive for something personally significant, whether it’s learning a new craft, changing careers, or raising moral children, are far happier than those who don’t have strong dreams or aspirations. Find a happy person, and you will find a project.”

Call it a project, goal, dream, aspiration, or whatever—you need something you’re working on and/or something you’re working toward.

Goals give you meaning, a sense of purpose, a feeling of control, and a positive outlook on life. They get us fired up and out of bed in the morning. They put us into that high-performance state of enthusiasm, positivity, and motivation.

If your life lacks meaning, if you’re bored a lot of the time, if you don’t know what to do with yourself, it’s likely because you’re not pursuing any projects you’re passionate about.

If you want greater happiness, figure out a worthwhile project and get on it. Happy people have projects.
