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

by James Clear

We all face challenges in life. This injury was one of mine, and the experience taught me a critical lesson: changes that seem small and unimportant at first will compound into remarkable results if you’re willing to stick with them for years.

Brailsford had been hired to put British Cycling on a new trajectory. What made him different from previous coaches was his relentless commitment to a strategy that he referred to as “the aggregation of marginal gains,” which was the philosophy of searching for a tiny margin of improvement in everything you do. Brailsford said, “The whole principle came from the idea that if you broke down everything you could think of that goes into riding a bike, and then improve it by 1 percent, you will get a significant increase when you put them all together.”

Habits are the compound interest of self-improvement. The same way that money multiplies through compound interest, the effects of your habits multiply as you repeat them. They seem to make little difference on any given day and yet the impact they deliver over the months and years can be enormous. It is only when looking back two, five, or perhaps ten years later that the value of good habits and the cost of bad ones becomes strikingly apparent.

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.

Time magnifies the margin between success and failure. It will multiply whatever you feed it. Good habits make time your ally. Bad habits make time your enemy.

Goals are about the results you want to achieve. Systems are about the processes that lead to those results.

The goal in any sport is to finish with the best score, but it would be ridiculous to spend the whole game staring at the scoreboard. The only way to actually win is to get better each day. In the words of three-time Super Bowl winner Bill Walsh, “The score takes care of itself.” The same is true for other areas of life. If you want better results, then forget about setting goals. Focus on your system instead.

What do I mean by this? Are goals completely useless? Of course not. Goals are good for setting a direction, but systems are best for making progress. A handful of problems arise when you

Achieving a goal only changes your life for the moment. That’s the counterintuitive thing about improvement.

Finally, a goal-oriented mind-set can create a “yo-yo” effect. Many runners work hard for months, but as soon as they cross the finish line, they stop training. The race is no longer there to motivate them. When all of your hard work is focused on a particular goal, what is left to push you forward after you achieve it? This is why many people find themselves reverting to their old habits after accomplishing a goal. The purpose of setting goals is to win the game. The purpose of building systems is to continue playing the game. True long-term thinking is goal-less thinking. It’s not about any single accomplishment. It is about the cycle of endless refinement and continuous improvement. Ultimately, it is your commitment to the process that will determine your progress.

You do not rise to the level of your goals. You fall to the level of your systems.

Behavior that is incongruent with the self will not last. You may want more money, but if your identity is someone who consumes rather than creates, then you’ll continue to be pulled toward spending rather than earning. You may want better health, but if you continue to prioritize comfort over accomplishment, you’ll be drawn to relaxing rather than training. It’s hard to change your habits if you never change the underlying beliefs that led to your past behavior. You have a new goal and a new plan, but you haven’t changed who you are.

The ultimate form of intrinsic motivation is when a habit becomes part of your identity. It’s one thing to say I’m the type of person who wants this. It’s something very different to say I’m the type of person who is this.

True behavior change is identity change. You might start a habit because of motivation, but the only reason you’ll stick with one is that it becomes part of your identity. Anyone can convince themselves to visit the gym or eat healthy once or twice, but if you don’t shift the belief behind the behavior, then it is hard to stick with long-term changes. Improvements are only temporary until they become part of who you are.

The goal is not to read a book, the goal is to become a reader.

Your behaviors are usually a reflection of your identity. What you do is an indication of the type of person you believe that you are—either consciously or nonconsciously.* Research has shown that once a person believes in a particular aspect of their identity, they are more likely to act in alignment with that belief. For example, people who identified as “being a voter” were more likely to vote than those who simply claimed “voting” was an action they wanted to perform.

Progress requires unlearning. Becoming the best version of yourself requires you to continuously edit your beliefs, and to upgrade and expand your identity.

Your identity emerges out of your habits. You are not born with preset beliefs. Every belief, including those about yourself, is learned and conditioned through experience.

More precisely, your habits are how you embody your identity. When you make your bed each day, you embody the identity of an organized person. When you write each day, you embody the identity of a creative person. When you train each day, you embody the identity of an athletic person. The more you repeat a behavior, the more you reinforce the identity associated with that behavior.

Whatever your identity is right now, you only believe it because you have proof of it. If you go to church every Sunday for twenty years, you have evidence that you are religious. If you study biology for one hour every night, you have evidence that you are studious. If you go to the gym even when it’s snowing, you have evidence that you are committed to fitness. The more evidence you have for a belief, the more strongly you will believe it.

improvements. Putting this all together, you can see that habits are the path to changing your identity. The most practical way to change who you are is to change what you do.

Decide the type of person you want to be. Prove it to yourself with small wins.

First, decide who you want to be. This holds at any level—as an individual, as a team, as a community, as a nation. What do you want to stand for? What are your principles and values? Who do you wish to become?

The focus should always be on becoming that type of person, not getting a particular outcome.

Identity change is the North Star of habit change.

From his studies, Thorndike described the learning process by stating, “behaviors followed by satisfying consequences tend to be repeated and those that produce unpleasant consequences are less likely to be repeated.”

Habit formation is incredibly useful because the conscious mind is the bottleneck of the brain. It can only pay attention to one problem at a time. As a result, your brain is always working to preserve your conscious attention for whatever task is most essential. Whenever possible, the conscious mind likes to pawn off tasks to the nonconscious mind to do automatically. This is precisely what happens when a habit is formed. Habits reduce cognitive load and free up mental capacity, so you can allocate your attention to other tasks.

Cravings are the second step, and they are the motivational force behind every habit. Without some level of motivation or desire—without craving a change—we have no reason to act. What you crave is not the habit itself but the change in state it delivers. You do not crave smoking a cigarette, you crave the feeling of relief it provides. You are not motivated by brushing your teeth but rather by the feeling of a clean mouth. You do not want to turn on the television, you want to be entertained. Every craving is linked to a desire to change your internal state. This is an important point that we will discuss in detail later.

How to Create a Good Habit The 1st law (Cue): Make it obvious. The 2nd law (Craving): Make it attractive. The 3rd law (Response): Make it easy. The 4th law (Reward): Make it satisfying.

How to Break a Bad Habit Inversion of the 1st law (Cue): Make it invisible. Inversion of the 2nd law (Craving): Make it unattractive. Inversion of the 3rd law (Response): Make it difficult. Inversion of the 4th law (Reward): Make it unsatisfying.

completely different strategies for each habit. Whenever you want to change your behavior, you can simply ask yourself: How can I make it obvious? How can I make it attractive? How can I make it easy? How can I make it satisfying?

For this reason, we must begin the process of behavior change with awareness.

If a habit remains mindless, you can’t expect to improve it. As the psychologist Carl Jung said, “Until you make the unconscious conscious, it will direct your life and you will call it fate.”

That’s the origin of the Habits Scorecard, which is a simple exercise you can use to become more aware of your behavior. To create your own, make a list of your daily habits. Here’s a sample of where your list might start: Wake up Turn off alarm Check my phone Go to the bathroom Weigh myself Take a shower Brush my teeth Floss my teeth Put on deodorant Hang up towel to dry Get dressed Make a cup of tea . . . and so on.

If you’re still having trouble determining how to rate a particular habit, here is a question I like to use: “Does this behavior help me become the type of person I wish to be? Does this habit cast a vote for or against my desired identity?” Habits that reinforce your desired identity are usually good. Habits that conflict with your desired identity are usually bad.

Hearing your bad habits spoken aloud makes the consequences seem more real. It adds weight to the action rather than letting yourself mindlessly slip into an old routine. This approach is useful even if you’re simply trying to remember a task on your to-do list. Just saying out loud, “Tomorrow, I need to go to the post office after lunch,” increases the odds that you’ll actually do it. You’re getting yourself to acknowledge the need for action—and that can make all the difference.

The sentence they filled out is what researchers refer to as an implementation intention, which is a plan you make beforehand about when and where to act. That is, how you intend to implement a particular habit.

The cues that can trigger a habit come in a wide range of forms—the feel of your phone buzzing in your pocket, the smell of chocolate chip cookies, the sound of ambulance sirens—but the two most common cues are time and location. Implementation intentions leverage both of these cues. Broadly speaking, the format for creating an implementation intention is: “When situation X arises, I will perform response Y.”

The simple way to apply this strategy to your habits is to fill out this sentence: I will [BEHAVIOR] at [TIME] in [LOCATION].

Meditation. I will meditate for one minute at 7 a.m. in my kitchen. Studying. I will study Spanish for twenty minutes at 6 p.m. in my bedroom. Exercise. I will exercise for one hour at 5 p.m. in my local gym. Marriage. I will make my partner a cup of tea at 8 a.m. in the kitchen. If you aren’t sure when to start your habit, try the first day of the week, month, or year. People are more likely to take action at those times because hope is usually higher. If we have hope, we have a reason to take action. A fresh start feels motivating.

Diderot’s behavior is not uncommon. In fact, the tendency for one purchase to lead to another one has a name: the Diderot Effect. The Diderot Effect states that obtaining a new possession often creates a spiral of consumption that leads to additional purchases. You

One of the best ways to build a new habit is to identify a current habit you already do each day and then stack your new behavior on top. This is called habit stacking.

Habit stacking is a special form of an implementation intention. Rather than pairing your new habit with a particular time and location, you pair it with a current habit. This method, which was created by BJ Fogg as part of his Tiny Habits program, can be used to design an obvious cue for nearly any habit.* The habit stacking formula is: “After [CURRENT HABIT], I will [NEW HABIT].”

Social skills. When I walk into a party, I will introduce myself to someone I don’t know yet. Finances. When I want to buy something over $100, I will wait twenty-four hours before purchasing. Healthy eating. When I serve myself a meal, I will always put veggies on my plate first. Minimalism. When I buy a new item, I will give something away. (“One in, one out.”) Mood. When the phone rings, I will take one deep breath and smile before answering. Forgetfulness. When I leave a public place, I will check the table and chairs to make sure I don’t leave anything behind.

Habits like “read more” or “eat better” are worthy causes, but these goals do not provide instruction on how and when to act. Be specific and clear: After I close the door. After I brush my teeth. After I sit down at the table. The specificity is important. The more tightly bound your new habit is to a specific cue, the better the odds are that you will notice when the time comes to act. The 1st Law of Behavior Change is to make it obvious. Strategies like implementation intentions and habit stacking are among the most practical ways to create obvious cues for your habits and design a clear plan for when and where to take action.

Environment is the invisible hand that shapes human behavior. Despite our unique personalities, certain behaviors tend to arise again and again under certain environmental conditions. In church, people tend to talk in whispers. On a dark street, people act wary and guarded. In this way, the most common form of change is not internal, but external: we are changed by the world around us. Every habit is context dependent.

The more obviously available a product or service is, the more likely you are to try it. People drink Bud Light because it is in every bar and visit Starbucks because it is on every corner. We like to think that we are in control. If we choose water over soda, we assume it is because we wanted to do so. The truth, however, is that many of the actions we take each day are shaped not by purposeful drive and choice but by the most obvious option.

The most powerful of all human sensory abilities, however, is vision. The human body has about eleven million sensory receptors. Approximately ten million of those are dedicated to sight. Some experts estimate that half of the brain’s resources are used on vision. Given that we are more dependent on vision than on any other sense, it should come as no surprise that visual cues are the greatest catalyst of our behavior. For this reason, a small change in what you see can lead to a big shift in what you do. As a result, you can imagine how important it is to live and work in environments that are filled with productive cues and devoid of unproductive ones.

Our behavior is not defined by the objects in the environment but by our relationship to them. In fact, this is a useful way to think about the influence of the environment on your behavior. Stop thinking about your environment as filled with objects. Start thinking about it as filled with relationships. Think in terms of how you interact with the spaces around you. For one person, her couch is the place where she reads for an hour each night. For someone else, the couch is where he watches television and eats a bowl of ice cream after work. Different people can have different memories—and thus different habits—associated with the same place. The good news? You can train yourself to link a particular habit with a particular context.

When you can’t manage to get to an entirely new environment, redefine or rearrange your current one. Create a separate space for work, study, exercise, entertainment, and cooking. The mantra I find useful is “One space, one use.”
