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

by James Clear

You should be far more concerned with your current trajectory than with your current results. If you’re a millionaire but you spend more than you earn each month, then you’re on a bad trajectory. If your spending habits don’t change, it’s not going to end well. Conversely, if you’re broke, but you save a little bit every month, then you’re on the path toward financial freedom—even if you’re moving slower than you’d like.

Your outcomes are a lagging measure of your habits. Your net worth is a lagging measure of your financial habits. Your weight is a lagging measure of your eating habits. Your knowledge is a lagging measure of your learning habits. Your clutter is a lagging measure of your cleaning habits. You get what you repeat.

Bamboo can barely be seen for the first five years as it builds extensive root systems underground before exploding ninety feet into the air within six weeks.

Every Olympian wants to win a gold medal. Every candidate wants to get the job. And if successful and unsuccessful people share the same goals, then the goal cannot be what differentiates the winners from the losers.

Achieving a goal only changes your life for the moment. That’s the counterintuitive thing about improvement. We think we need to change our results, but the results are not the problem. What we really need to change are the systems that cause those results.

The implicit assumption behind any goal is this: “Once I reach my goal, then I’ll be happy.” The problem with a goals-first mentality is that you’re continually putting happiness off until the next milestone. I’ve slipped into this trap so many times I’ve lost count. For years, happiness was always something for my future self to enjoy. I promised myself that once I gained twenty pounds of muscle or after my business was featured in the New York Times, then I could finally relax.

Imagine two people resisting a cigarette. When offered a smoke, the first person says, “No thanks. I’m trying to quit.” It sounds like a reasonable response, but this person still believes they are a smoker who is trying to be something else. They are hoping their behavior will change while carrying around the same beliefs. The second person declines by saying, “No thanks. I’m not a smoker.” It’s a small difference, but this statement signals a shift in identity. Smoking was part of their former life, not their current one. They no longer identify as someone who smokes.

Rewards are the end goal of every habit. The cue is about noticing the reward. The craving is about wanting the reward. The response is about obtaining the reward. We chase rewards because they serve two purposes: (1) they satisfy us and (2) they teach us.

Second, rewards teach us which actions are worth remembering in the future. Your brain is a reward detector. As you go about your life, your sensory nervous system is continuously monitoring which actions satisfy your desires and deliver pleasure. Feelings of pleasure and disappointment are part of the feedback mechanism that helps your brain distinguish useful actions from useless ones.11 Rewards close the feedback loop and complete the habit cycle.

In summary, the cue triggers a craving, which motivates a response, which provides a reward, which satisfies the craving and, ultimately, becomes associated with the cue. Together, these four steps form a neurological feedback loop—cue, craving, response, reward; cue, craving, response, reward—that ultimately allows you to create automatic habits. This cycle is known as the habit loop.

If your space is limited, divide your room into activity zones: a chair for reading, a desk for writing, a table for eating. You can do the same with your digital spaces. I know a writer who uses his computer only for writing, his tablet only for reading, and his phone only for social media and texting. Every habit should have a home. If you can manage to stick with this strategy, each context will become associated with a particular habit and mode of thought. Habits thrive under predictable circumstances like these. Focus comes automatically when you are sitting at your work desk. Relaxation is easier when you are in a space designed for that purpose. Sleep comes quickly when it is the only thing that happens in your bedroom.

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.

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.10 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.11 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.

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.

We imitate the habits of three groups in particular:2 The close. The many. The powerful.

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.

The normal behavior of the tribe often overpowers the desired behavior of the 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.

Some of our underlying motives include:fn1 ■ 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 A craving is just a specific manifestation of a deeper underlying motive. Your brain did not evolve with a desire to smoke cigarettes or to check Instagram or to play video games. At a deep level, you simply want to reduce uncertainty and relieve anxiety, to win social acceptance and approval, or to achieve status. 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 ■ Achieve status and prestige = playing video games Your habits are modern-day solutions to ancient desires. New versions of old vices. The underlying motives behind human behavior remain the same. The specific habits we perform differ based on the period of history. Here’s the powerful part: there are many different ways to address the same underlying motive. One person might learn to reduce stress by smoking a cigarette. Another person learns to ease their anxiety by going for a run. Your current habits are not necessarily the best way to solve the problems you face; they are ...

the specific cravings you feel and habits you perform are really an attempt to address your fundamental underlying motives. Whenever a habit successfully addresses

There is nothing magical about time passing with regard to habit formation. It doesn’t matter if it’s been twenty-one days or thirty days or three hundred days. What matters is the rate at which you perform the behavior. You could do something twice in thirty days, or two hundred times. It’s the frequency that makes the difference. Your current habits have been internalized over the course of hundreds, if not thousands, of repetitions. New habits require the same level of frequency.

Imagine you are holding a garden hose that is bent in the middle.3 Some water can flow through, but not very much. If you want to increase the rate at which water passes through the hose, you have two options. The first option is to crank up the valve and force more water out. The second option is to simply remove the bend in the hose and let water flow through naturally. Trying to pump up your motivation to stick with a hard habit is like trying to force water through a bent hose. You can do it, but it requires a lot of effort and increases the tension in your life. Meanwhile, making your habits simple and easy is like removing the bend in the hose. Rather than trying to overcome the friction in your life, you reduce it.

You can also invert this principle and prime the environment to make bad behaviors difficult. If you find yourself watching too much television, for example, then unplug it after each use. Only plug it back in if you can say out loud the name of the show you want to watch. This setup creates just enough friction to prevent mindless viewing. If that doesn’t do it, you can take it a step further. Unplug the television and take the batteries out of the remote after each use, so it takes an extra ten seconds to turn it back on. And if you’re really hard-core, move the television out of the living room and into a closet after each use. You can be sure you’ll only take it out when you really want to watch something. The greater the friction, the less likely the habit.

Whenever possible, I leave my phone in a different room until lunch. When it’s right next to me, I’ll check it all morning for no reason at all. But when it is in another room, I rarely think about it. And the friction is high enough that I won’t go get it without a reason. As a result, I get three to four hours each morning when I can work without interruption.

Whether we are approaching behavior change as an individual, a parent, a coach, or a leader, we should ask ourselves the same question: “How can we design a world where it’s easy to do what’s right?” Redesign your life so the actions that matter most are also the actions that are easiest to do.

Human behavior follows the Law of Least Effort. We will naturally gravitate toward the option that requires the least amount of work. ■ Create an environment where doing the right thing is as easy as possible. ■ Reduce the friction associated with good behaviors. When friction is low, habits are easy. ■ Increase the friction associated with bad behaviors. When friction is high, habits are difficult.

Even when you know you should start small, it’s easy to start too big. When you dream about making a change, excitement inevitably takes over and you end up trying to do too much too soon. The most effective way I know to counteract this tendency is to use the Two-Minute Rule, which states, “When you start a new habit, it should take less than two minutes to do.”

For instance, running a marathon is very hard. Running a 5K is hard. Walking ten thousand steps is moderately difficult. Walking ten minutes is easy. And putting on your running shoes is very easy.

People often think it’s weird to get hyped about reading one page or meditating for one minute or making one sales call. But the point is not to do one thing. The point is to master the habit of showing up. The truth is, a habit must be established before it can be improved. If you can’t learn the basic skill of showing up, then you have little hope of mastering the finer details. Instead of trying to engineer a perfect habit from the start, do the easy thing on a more consistent basis. You have to standardize before you can optimize.

If the Two-Minute Rule feels forced, try this: do it for two minutes and then stop. Go for a run, but you must stop after two minutes. Start meditating, but you must stop after two minutes. Study Arabic, but you must stop after two minutes. It’s not a strategy for starting, it’s the whole thing. Your habit can only last one hundred and twenty seconds.

Sometimes success is less about making good habits easy and more about making bad habits hard. This is an inversion of the 3rd Law of Behavior Change: make it difficult. If you find yourself continually struggling to follow through on your plans, then you can take a page from Victor Hugo and make your bad habits more difficult by creating what psychologists call a commitment device. A commitment device is a choice you make in the present that controls your actions in the future.2 It is a way to lock in future behavior, bind you to good habits, and restrict you from bad ones. When Victor Hugo shut his clothes away so he could focus on writing, he was creating a commitment device.4 fn2 There are many ways to create a commitment device. You can reduce overeating by purchasing food in individual packages rather than in bulk size. You can voluntarily ask to be added to the banned list at casinos and online poker sites to prevent future gambling sprees. I’ve even heard of athletes who have to “make weight” for a competition choosing to leave their wallets at home during the week before weigh-in so they won’t be tempted to buy fast food.

Cardinal Rule of Behavior Change: What is rewarded is repeated. What is punished is avoided. You learn what to do in the future based on what you were rewarded for doing (or punished for doing) in the past. Positive emotions cultivate habits. Negative emotions destroy them.

The first three laws of behavior change—make it obvious, make it attractive, and make it easy—increase the odds that a behavior will be performed this time. The fourth law of behavior change—make it satisfying—increases the odds that a behavior will be repeated next time. It completes the habit loop. But there is a trick. We are not looking for just any type of satisfaction. We are looking for immediate satisfaction.

You value the present more than the future. Usually, this tendency serves us well. A reward that is certain right now is typically worth more than one that is merely possible in the future.

Why would someone smoke if they know it increases the risk of lung cancer? Why would someone overeat when they know it increases their risk of obesity? Why would someone have unsafe sex if they know it can result in sexually transmitted disease? Once you understand how the brain prioritizes rewards, the answers become clear: the consequences of bad habits are delayed while the rewards are immediate. Smoking might kill you in ten years, but it reduces stress and eases your nicotine cravings now. Overeating is harmful in the long run but appetizing in the moment. Sex—safe or not—provides pleasure right away. Disease and infection won’t show up for days or weeks, even years.

Every habit produces multiple outcomes across time. Unfortunately, these outcomes are often misaligned. With our bad habits, the immediate outcome usually feels good, but the ultimate outcome feels bad. With good habits, it is the reverse: the immediate outcome is unenjoyable, but the ultimate outcome feels good.

“Don’t break the chain” is a powerful mantra. Don’t break the chain of sales calls and you’ll build a successful book of business. Don’t break the chain of workouts and you’ll get fit faster than you’d expect. Don’t break the chain of creating every day and you will end up with an impressive portfolio.

Habit tracking also helps keep your eye on the ball: you’re focused on the process rather than the result. You’re not fixated on getting six-pack abs, you’re just trying to keep the streak alive and become the type of person who doesn’t miss workouts.

You don’t realize how valuable it is to just show up on your bad (or busy) days. Lost days hurt you more than successful days help you. If you start with $100, then a 50 percent gain will take you to $150. But you only need a 33 percent loss to take you back to $100. In other words, avoiding a 33 percent loss is just as valuable as achieving a 50 percent gain. As Charlie Munger says, “The first rule of compounding: Never interrupt it unnecessarily.” This is why the “bad” workouts are often the most important ones. Sluggish days and bad workouts maintain the compound gains you accrued from previous good days. Simply doing something—ten squats, five sprints, a push-up, anything really—is huge. Don’t put up a zero. Don’t let losses eat into your compounding.

All of this to say, it’s crucial to keep habit tracking in its proper place. It can feel satisfying to record a habit and track your progress, but the measurement is not the only thing that matters. Furthermore, there are many ways to measure progress, and sometimes it helps to shift your focus to something entirely different. This is why nonscale victories can be effective for weight loss. The number on the scale may be stubborn, so if you focus solely on that number, your motivation will sag. But you may notice that your skin looks better or you wake up earlier or your sex drive got a boost. All of these are valid ways to track your improvement. If you’re not feeling motivated by the number on the scale, perhaps it’s time to focus on a different measurement—one that gives you more signals of progress.

“My suggestion was quite simple,” he wrote in 1981. “Put that [nuclear] code number in a little capsule, and then implant that capsule right next to the heart of a volunteer. The volunteer would carry with him a big, heavy butcher knife as he accompanied the President. If ever the President wanted to fire nuclear weapons, the only way he could do so would be for him first, with his own hands, to kill one human being. The President says, ‘George, I’m sorry but tens of millions must die.’ He has to look at someone and realize what death is—what an innocent death is. Blood on the White House carpet. It’s reality brought home.

The more immediate the pain, the less likely the behavior. If you want to prevent bad habits and eliminate unhealthy behaviors, then adding an instant cost to the action is a great way to reduce their odds.

You can even automate this process. Thomas Frank, an entrepreneur in Boulder, Colorado, wakes up at 5:55 each morning.7 And if he doesn’t, he has a tweet automatically scheduled that says, “It’s 6:10 and I’m not up because I’m lazy! Reply to this for $5 via PayPal (limit 5), assuming my alarm didn’t malfunction.”

The most proven scientific analysis of personality traits is known as the “Big Five,” which breaks them down into five spectrums of behavior. Openness to experience: from curious and inventive on one end to cautious and consistent on the other. Conscientiousness: organized and efficient to easygoing and spontaneous. Extroversion: outgoing and energetic to solitary and reserved (you likely know them as extroverts vs. introverts). Agreeableness: friendly and compassionate to challenging and detached. Neuroticism: anxious and sensitive to confident, calm, and stable.

All five characteristics have biological underpinnings. Extroversion, for instance, can be tracked from birth. If scientists play a loud noise in the nursing ward, some babies turn toward it while others turn away. When the researchers tracked these children through life, they found that the babies who turned toward the noise were more likely to grow up to be extroverts. Those who turned away were more likely to become introverts.

If you can’t find a game where the odds are stacked in your favor, create one. Scott Adams, the cartoonist behind Dilbert, says, “Everyone has at least a few areas in which they could be in the top 25% with some effort.20 In my case, I can draw better than most people, but I’m hardly an artist. And I’m not any funnier than the average standup comedian who never makes it big, but I’m funnier than most people. The magic is that few people can draw well and write jokes. It’s the combination of the two that makes what I do so rare. And when you add in my business background, suddenly I had a topic that few cartoonists could hope to understand without living it.”

Furthermore, genes can’t make you successful if you’re not doing the work. Yes, it’s possible that the ripped trainer at the gym has better genes, but if you haven’t put in the same reps, it’s impossible to say if you have been dealt a better or worse genetic hand. Until you work as hard as those you admire, don’t explain away their success as luck.

The human brain loves a challenge, but only if it is within an optimal zone of difficulty. If you love tennis and try to play a serious match against a four-year-old, you will quickly become bored. It’s too easy. You’ll win every point. In contrast, if you play a professional tennis player like Roger Federer or Serena Williams, you will quickly lose motivation because the match is too difficult.

The Goldilocks Rule states that humans experience peak motivation when working on tasks that are right on the edge of their current abilities. Not too hard. Not too easy. Just right.

“What’s the difference between the best athletes and everyone else?” I asked. “What do the really successful people do that most don’t?” He mentioned the factors you might expect: genetics, luck, talent. But then he said something I wasn’t expecting: “At some point it comes down to who can handle the boredom of training every day, doing the same lifts over and over and over.” His answer surprised me because it’s a different way of thinking about work ethic. People talk about getting “amped up” to work on their goals. Whether it’s business or sports or art, you hear people say things like, “It all comes down to passion.” Or, “You have to really want it.” As a result, many of us get depressed when we lose focus or motivation because we think that successful people have some bottomless reserve of passion. But this coach was saying that really successful people feel the same lack of motivation as everyone else. The difference is that they still find a way to show up despite the feelings of boredom.
