Atomic Habits: An Easy & Proven Way to Build Good Habits & Break Bad Ones

by James Clear

This is the secret to self-control. Make the cues of your good habits obvious and the cues of your bad habits invisible. Chapter Summary The inversion of the 1st Law of Behavior Change is make it invisible. Once a habit is formed, it is unlikely to be forgotten. People with high self-control tend to spend less time in tempting situations. It’s easier to avoid temptation than resist it. One of the most practical ways to eliminate a bad habit is to reduce exposure to the cue that causes it. Self-control is a short-term strategy, not a long-term one.

A supernormal stimulus is a heightened version of reality—like a beak with three red dots or an egg the size of a volleyball—and it elicits a stronger response than usual.

Humans are also prone to fall for exaggerated versions of reality. Junk food, for example, drives our reward systems into a frenzy. After spending hundreds of thousands of years hunting and foraging for food in the wild, the human brain has evolved to place a high value on salt, sugar, and fat. Such foods are often calorie-dense and they were quite rare when our ancient ancestors were roaming the savannah. When you don’t know where your next meal is coming from, eating as much as possible is an excellent strategy for survival. Today, however, we live in a calorie-rich environment.

A primary goal of food science is to create products that are more attractive to consumers. Nearly every food in a bag, box, or jar has been enhanced in some way, if only with additional flavoring. Companies spend millions of dollars to discover the most satisfying level of crunch in a potato chip or the perfect amount of fizz in a soda. Entire departments are dedicated to optimizing how a product feels in your mouth—a quality known as orosensation. French fries, for example, are a potent combination—golden brown and crunchy on the outside, light and smooth on the inside.

Throughout our discussion of the 2nd Law, our goal is to learn how to make our habits irresistible. While it is not possible to transform every habit into a supernormal stimulus, we can make any habit more enticing. To do this, we must start by understanding what a craving is and how it works. We begin by examining a biological signature that all habits share—the dopamine spike.

The importance of dopamine became apparent in 1954 when the neuroscientists James Olds and Peter Milner ran an experiment that revealed the neurological processes behind craving and desire. By implanting electrodes in the brains of rats, the researchers blocked the release of dopamine. To the surprise of the scientists, the rats lost all will to live. They wouldn’t eat. They wouldn’t have sex. They didn’t crave anything. Within a few days, the animals died of thirst.

In follow-up studies, other scientists also inhibited the dopamine-releasing parts of the brain, but this time, they squirted little droplets of sugar into the mouths of the dopamine-depleted rats. Their little rat faces lit up with pleasurable grins from the tasty substance. Even though dopamine was blocked, they liked the sugar just as much as before; they just didn’t want it anymore. The ability to experience pleasure remained, but without dopamine, desire died. And without desire, action stopped. When other researchers reversed this process and flooded the reward system of the brain with dopamine, animals performed habits at breakneck speed. In one study, mice received a powerful hit of dopamine each time they poked their nose in a box. Within minutes, the mice developed a craving so strong they began poking their nose into the box eight hundred times per hour. (Humans are not so different: the average slot machine player will spin the wheel six hundred times per hour.)

scientists assumed dopamine was all about pleasure, but now we know it plays a central role in many neurological processes, including motivation, learning and memory, punishment and aversion, and voluntary movement.

When it comes to habits, the key takeaway is this: dopamine is released not only when you experience pleasure, but also when you anticipate it. Gambling addicts have a dopamine spike right before they place a bet, not after they win. Cocaine addicts get a surge of dopamine when they see the powder, not after they take it. Whenever you predict that an opportunity will be rewarding, your levels of dopamine spike in anticipation. And whenever dopamine rises, so does your motivation to act.

Before a habit is learned (A), dopamine is released when the reward is experienced for the first time. The next time around (B), dopamine rises before taking action, immediately after a cue is recognized. This spike leads to a feeling of desire and a craving to take action whenever the cue is spotted. Once a habit is learned, dopamine will not rise when a reward is experienced because you already expect the reward. However, if you see a cue and expect a reward, but do not get one, then dopamine will drop in disappointment (C). The sensitivity of the dopamine response can clearly be seen when a reward is provided late (D). First, the cue is identified and dopamine rises as a craving builds. Next, a response is taken but the reward does not come as quickly as expected and dopamine begins to drop. Finally, when the reward comes a little later than you had hoped, dopamine spikes again. It is as if the brain is saying, “See! I knew I was right. Don’t forget to repeat this action next time.”

Your brain has far more neural circuitry allocated for wanting rewards than for liking them. The wanting centers in the brain are large: the brain stem, the nucleus accumbens, the ventral tegmental area, the dorsal striatum, the amygdala, and portions of the prefrontal cortex. By comparison, the liking centers of the brain are much smaller. They are often referred to as “hedonic hot spots” and are distributed like tiny islands throughout the brain.

Ronan Byrne, an electrical engineering student in Dublin, Ireland, enjoyed watching Netflix, but he also knew that he should exercise more often than he did. Putting his engineering skills to use, Byrne hacked his stationary bike and connected it to his laptop and television. Then he wrote a computer program that would allow Netflix to run only if he was cycling at a certain speed. If he slowed down for too long, whatever show he was watching would pause until he started pedaling again. He was, in the words of one fan, “eliminating obesity one Netflix binge at a time.” He was also

You’re more likely to find a behavior attractive if you get to do one of your favorite things at the same time. Perhaps you want to hear about the latest celebrity gossip, but you need to get in shape. Using temptation bundling, you could only read the tabloids and watch reality shows at the gym. Maybe you want to get a pedicure, but you need to clean out your email inbox. Solution: only get a pedicure while processing overdue work emails.

You can even combine temptation bundling with BJ Fogg’s habit stacking strategy we discussed in Chapter 5 to create a set of rules to guide your behavior. The habit stacking + temptation bundling formula is: After I [CURRENT HABIT], I will [HABIT I NEED]. After [HABIT I NEED], I will [HABIT I WANT].

The 2nd Law of Behavior Change is make it attractive. The more attractive an opportunity is, the more likely it is to become habit-forming. Habits are a dopamine-driven feedback loop. When dopamine rises, so does our motivation to act. It is the anticipation of a reward—not the fulfillment of it—that gets us to take action. The greater the anticipation, the greater the dopamine spike. Temptation bundling is one way to make your habits more attractive. The strategy is to pair an action you want to do with an action you need to do.

The Polgar sisters grew up in a culture that prioritized chess above all else—praised them for it, rewarded them for it. In their world, an obsession with chess was normal. And as we are about to see, whatever habits are normal in your culture are among the most attractive behaviors you’ll find.

Meanwhile, those who collaborated and bonded with others enjoyed increased safety, mating opportunities, and access to resources. As Charles Darwin noted, “In the long history of humankind, those who learned to collaborate and improvise most effectively have prevailed.” As a result, one of the deepest human desires is to belong. And this ancient preference exerts a powerful influence on our modern behavior.

As the French philosopher Michel de Montaigne wrote, “The customs and practices of life in society sweep us along.”

We imitate the habits of three groups in particular: The close. The many. The powerful.

I find that I often imitate the behavior of those around me without realizing it. In conversation, I’ll automatically assume the body posture of the other person. In college, I began to talk like my roommates. When traveling to other countries, I unconsciously imitate the local accent despite reminding myself to stop. As a general rule,

your goal was to make it into space, then that room was about the best culture you could ask for. Similarly, one study found that the higher your best friend’s IQ at age eleven or twelve, the higher your IQ would be at age fifteen, even after controlling for natural levels of intelligence. We soak up the qualities and practices of those around us.

One of the most effective things you can do to build better habits is to join a culture where your desired behavior is the normal behavior. New habits seem achievable when you see others doing them every day. If you are surrounded by fit people, you’re more likely to consider working out to be a common habit. If you’re surrounded by jazz lovers, you’re more likely to believe it’s reasonable to play jazz every day. Your culture sets your expectation for what is “normal.” Surround yourself with people who have the habits you want to have yourself. You’ll rise together.

Join a culture where (1) your desired behavior is the normal behavior and (2) you already have something in common with the group. Steve Kamb, an entrepreneur in New York City, runs a company called Nerd Fitness, which “helps nerds, misfits, and mutants lose weight, get strong, and get healthy.” His clients include video game lovers, movie fanatics, and average Joes who want to get in shape. Many people feel out of place the first time they go to the gym or try to change their diet, but if you are already similar to the other members of the group in some way—say, your mutual love of Star Wars—change becomes more appealing because it feels like something people like you already do.

Whenever we are unsure how to act, we look to the group to guide our behavior. We are constantly scanning our environment and wondering, “What is everyone else doing?” We check reviews on Amazon or Yelp or TripAdvisor because we want to imitate the “best” buying, eating, and travel habits. It’s usually a smart strategy. There is evidence in numbers.

individual. For example, one study found that when a chimpanzee learns an effective way to crack nuts open as a member of one group and then switches to a new group that uses a less effective strategy, it will avoid using the superior nut cracking method just to blend in with the rest of the chimps.

When changing your habits means challenging the tribe, change is unattractive. When changing your habits means fitting in with the tribe, change is very attractive.

We are drawn to behaviors that earn us respect, approval, admiration, and status. We want to be the one in the gym who can do muscle-ups or the musician who can play the hardest chord progressions or the parent with the most accomplished children because these things separate us from the crowd. Once we fit in, we start looking for ways to stand out.

The Polgar sisters—the chess prodigies mentioned at the beginning of this chapter—are evidence of the powerful and lasting impact social influences can have on our behavior. The sisters practiced chess for many hours each day and continued this remarkable effort for decades. But these habits and behaviors maintained their attractiveness, in part, because they were valued by their culture. From the praise of their parents to the achievement of different status markers like becoming a grandmaster, they had many reasons to continue their effort.

The culture we live in determines which behaviors are attractive to us. We tend to adopt habits that are praised and approved of by our culture because we have a strong desire to fit in and belong to the tribe. We tend to imitate the habits of three social groups: the close (family and friends), the many (the tribe), and the powerful (those with status and prestige). One of the most effective things you can do to build better habits is to join a culture where (1) your desired behavior is the normal behavior and (2) you already have something in common with the group. The normal behavior of the tribe often overpowers the desired behavior of the individual. Most days, we’d rather be wrong with the crowd than be right by ourselves. If a behavior can get us approval, respect, and praise, we find it attractive.

look at the book afterward out of curiosity. The author employs an interesting strategy to help smokers eliminate their cravings. He systematically reframes each cue associated with smoking and gives it a new meaning. He says things like: You think you are quitting something, but you’re not quitting anything because cigarettes do nothing for you. You think smoking is something you need to do to be social, but it’s not. You can be social without smoking at all. You think smoking is about relieving stress, but it’s not. Smoking does not relieve your nerves, it destroys them. Over and over, he repeats these phrases and others like them.

your mind,” he says. “You are losing nothing

By the time you get to the end of the book, smoking seems like the most ridiculous thing in the world to do. And if you no longer expect smoking to bring you any benefits, you have no reason to smoke. It is an inversion of the 2nd Law of Behavior Change: make it unattractive.

Some of our underlying motives include:* Conserve energy Obtain food and water Find love and reproduce Connect and bond with others Win social acceptance and approval Reduce uncertainty Achieve status and prestige

Look at nearly any product that is habit-forming and you’ll see that it does not create a new motivation, but rather latches onto the underlying motives of human nature.

Find love and reproduce = using Tinder Connect and bond with others = browsing Facebook Win social acceptance and approval = posting on Instagram Reduce uncertainty = searching on Google

Desire is the difference between where you are now and where you want to be in the future. Even the tiniest action is tinged with the motivation to feel differently than you do in the moment. When you binge-eat or light up or browse social media, what you really want is not a potato chip or a cigarette or a bunch of likes. What you really want is to feel different.

To summarize, the specific cravings you feel and habits you perform are really an attempt to address your fundamental underlying motives. Whenever a habit successfully addresses a motive, you develop a craving to do it again. In time, you learn to predict that checking social media will help you feel loved or that watching YouTube will allow you to forget your fears. Habits are attractive when we associate them with positive feelings, and we can use this insight to our advantage rather than to our detriment.

shift. For instance, we often talk about everything we have to do in a given day. You have to wake up early for work. You have to make another sales call for your business. You have to cook dinner for your family. Now, imagine changing just one word: You don’t “have” to. You “get” to. You get to wake up early for work. You get to make another sales call for your business. You get to cook dinner for your family. By simply changing one word, you shift the way you view each event. You transition from seeing these behaviors as burdens and turn them into opportunities. The key point is that both

uses a wheelchair. When asked if it was difficult being confined, he responded, “I’m not confined to my wheelchair—I am liberated by it. If it wasn’t for my wheelchair, I would be bed-bound and never able to leave my house.” This shift in perspective completely transformed how he lived each day. Reframing your habits to highlight their benefits rather than their drawbacks is a fast and lightweight way to reprogram your mind and make a habit seem more attractive.

Finance. Saving money is often associated with sacrifice. However, you can associate it with freedom rather than limitation if you realize one simple truth: living below your current means increases your future means. The money you save this month increases your purchasing power next month.

You can adapt this strategy for nearly any purpose. Say you want to feel happier in general. Find something that makes you truly happy—like petting your dog or taking a bubble bath—and then create a short routine that you perform every time before you do the thing you love. Maybe you take three deep breaths and smile. Three deep breaths. Smile. Pet the dog. Repeat. Eventually, you’ll begin to associate this breathe-and-smile routine with being in a good mood. It becomes a cue that means feeling happy. Once established, you can break it out

Lol, did he just teach someone how to feel happiness?

Chapter Summary The inversion of the 2nd Law of Behavior Change is make it unattractive. Every behavior has a surface level craving and a deeper underlying motive. Your habits are modern-day solutions to ancient desires. The cause of your habits is actually the prediction that precedes them. The prediction leads to a feeling. Highlight the benefits of avoiding a bad habit to make it seem unattractive. Habits are attractive when we associate them with positive feelings and unattractive when we associate them with negative feelings. Create a motivation ritual by doing something you enjoy immediately before a difficult habit.

ON THE FIRST day of class, Jerry Uelsmann, a professor at the University of Florida, divided his film photography students into two groups. Everyone on the left side of the classroom, he explained, would be in the “quantity” group. They would be graded solely on the amount of work they produced. On the final day of class, he would tally the number of photos submitted by each student. One hundred photos would rate an A, ninety photos a B, eighty photos a C, and so on. Meanwhile, everyone on the right side of the room would be in the “quality” group. They would be graded only on the excellence of their work. They would only need to produce one photo during the semester, but to get an A, it had to be a nearly perfect image. At the end of the term, he was surprised to find that all the best photos were produced by the quantity group. During the semester, these students were busy taking photos, experimenting with composition and lighting, testing out various methods in the darkroom, and learning from their mistakes. In the process of creating hundreds of photos, they honed their skills. Meanwhile, the quality group sat around speculating about perfection. In the end, they had little to show for their efforts other than unverified theories and one mediocre photo.*

being in motion and taking action. The two ideas sound similar, but they’re not the same. When you’re in motion, you’re planning and strategizing and learning. Those are all good things, but they don’t produce a result. Action, on the other hand, is the type of behavior that will deliver an outcome. If I outline twenty ideas for articles I want to write, that’s motion. If I actually sit down and write an article, that’s action.

Sometimes motion is useful, but it will never produce an outcome by itself. It doesn’t matter how many times you go talk to the personal trainer, that motion will never get you in shape. Only the action of working out will get the result you’re looking to achieve.
