1-Page Summary

More than 50% of your actions on any given day are automatic actions, or habits. These habits have been formed through repeated actions over the course of your life, and some serve you and some work against you. Because of their significant role in your life, understanding what habits are, how to change them, and how they shape who you are is important. In Atomic Habits, James Clear provides every aspect involved in forming new habits, breaking bad ones, and transforming your life for long-term success.

Small Adjustments Lead to Massive Transformations

Behavior does not happen in a vacuum. Each action creates a path that leads to other actions. Which actions or behaviors you perform dictate which actions or behaviors will follow. This is why forming good habits is so important. When you start with good behaviors, more good behaviors will follow.

This idea is grounded in the concept of compounding behaviors and is the essence of Atomic Habits. Atomic habits are small 1% improvements in behavior that, over time, compound into full-blown behavior change and positive habits.

To make the most of small increases, you need to adjust how you think about behavior change. There are three directions by which you approach behavior change: outcome-driven, process-driven, and identity-driven changes.

Outcome-Driven Habits

Outcomes are synonymous with goals. They represent the end result you wish to achieve through your behaviors. When you focus on the end goal of your behaviors, you tend to do whatever is necessary to achieve that goal. But those behaviors may not be the most beneficial or capable of being repeated long-term. Further, once the goal is achieved, there is no reason to continue those specific behaviors. If you adapt your actions to serve one finite purpose, your actions also become finite.

  • For example, you may decide you want to have six-pack abs. You decide that doing crunches will lead to that outcome. You do 100 crunches a day until you have six-pack abs. Now that you have the abs you want, 100 crunches start to seem like a burden, and you lose motivation to do them because they are not connected with a goal.

Process-Based Habits

Processes are synonymous with systems. Within every long-term goal is a system of behaviors that link up to reach the desired outcome. Focusing on a systemic level pushes you to form habits that continually lead to successful results, thereby becoming more inherent, continual, and positive in the long-term.

When you focus on systemic level changes, you’ll make small positive adjustments in your actions, rather than performing one big action.

Identity-Based Habits

Identity is synonymous with who you are and how you live. Within your identity lies characteristics. When you approach habit change through this lens, you focus on forming behaviors that match the characteristics of the type of person you want to be. This direction is closely aligned with systems, in that the systems required to reach your chosen identity are informed by the characteristics of that identity.

  • Using the six-pack abs example, you determine that someone with six-pack abs must have a healthy lifestyle. Therefore, you desire to become someone with a healthy lifestyle. You decide that a combination of 10 crunches before bed, a low-calorie diet, and riding a bike instead of driving to work equals a healthy lifestyle. Over time, continuing to perform these actions leads to an overall healthier body that includes six-pack abs. Now, you have the abs you wanted and the habit of living more healthily.

When you work through the processes of your chosen identity, you stop being someone waiting to achieve a certain goal and start living as someone capable of achieving that goal over and over again.

Outcome-driven habits help you win the game. Process-driven habits teach you how to play the game and keep playing. Identity-driven habits help you decide which game to play. So work in reverse—start with your desired identity to find the right habits that lead to the right results.

How Do Habits Form?

The reason you continue to repeat certain behaviors relates to the way the brain takes in the associated information. Your brain understands behaviors as four separate stages that, when added together, lead to habits.

Four Stages of Habit Formation

These stages are the cue, the craving, the response, and the reward. Every habit you have is linked to these four stages.

The cue is the element that triggers the brain to notice an opportunity for a reward, or pleasure. A cue can be a smell, a sound, an event, an interaction, or anything else that triggers a desire. This desire is known as the craving.

The craving is the emotional relevance attached to a certain cue. When you notice the cue, the brain anticipates an opportunity for a change in your physical or emotional state. You crave the satisfaction that change will elicit, and this craving is what prompts you to act.

The response is the actual behavior, or habit, performed to elicit the change you desire. Your brain prompts you to take a certain action it believes will create the feeling of satisfaction you want.

The reward is the satisfaction gained from the action taken. You have successfully satisfied your craving and changed your physical or emotional state. The brain builds a pathway from the cue to this state of pleasure. Every time you experience the same cue, the brain will be triggered to desire that pleasure again. You will be prompted to perform the same action, thereby creating a habit.

The process works like this: Cue: You walk past a coffee shop on the way to work and smell fresh roasted coffee. Craving: Coffee gives you energy, and you want to feel energized. Response: You buy a cup of coffee. Reward: By the time you reach work, you are raring to go. Buying a cup of coffee becomes associated with your walk to work.

If one of these stages fails, the habit will not be formed.

  • If you remove the cue, your brain is not activated.
  • If you remove the craving, you have no need to act.
  • If the response is too hard, you won’t be able to do it or won’t try.
  • If the reward is not satisfying, you have no reason to want to attain it again.

You can use this information to form or break habits by altering the various stages to your advantage. Each stage encompasses a law that guides you in that endeavor.

Four Laws of Habit Formation

Think of these laws as a framework for designing each stage for optimal habit formation.

Cue: Make It Obvious

Because habits are automatic behaviors, you likely don’t notice every cue triggering you to act. Therefore, the first step in creating cues that lead to good behaviors is to become aware of them.

Become Aware of Habits

Make a habit scorecard to list all your current habits performed daily. Because behaviors influence each other, the end of one habit often serves as a cue for another. When you list your habits, you’re able to see which actions precede them and which follow. By listing your cues and rewards in this way, you will see what current behaviors may be suitable to cue new desired behaviors.

Use Awareness to Your Advantage

You can exploit the habit scorecard in two ways to form better habits.

The first is implementation intention, wherein you make an advanced plan for a new behavior by assigning a specific time and place for it. Research suggests that activities set for specific times are more likely to be followed through.

  • If your scorecard shows a gap in activities between 12:30 pm and 1:30 pm, you might find an opportunity to schedule a new behavior during that time.
  • You decide that at 12:30 pm, you will walk around the block for 20 minutes to exercise. Each day at 12:30, you will be prompted to walk.
  • The formula is: “When X occurs, I will do Y” or “At X time, I will do Y.”

This strategy makes the cue obvious by attributing a specific time and place to the behavior.

The second is habit stacking. This technique links a new behavior to a current one by allowing the reward to become the new cue.

  • Rather than setting a specific time for your walk, you decide you will walk every day after lunch. The end of lunch now becomes the cue to walk.
  • The formula is: “After I do X, I will do Y.”

This strategy makes the cue obvious by attaching a desired habit to a fully formed habit.

The most important elements involved in making a cue obvious are 1) to be as specific as possible in the behavior that will follow and 2) ensure that the cue is realistic.

  • Saying, “I will walk on my lunch break” is less specific than “I will walk around the block [specific location] after eating lunch [specific cue] for 20 minutes [specific intention].” The new action is easier to take when the questions about where, when, and how are already answered.
  • However, if you only have 30 minutes for lunch, planning a 20-minute walk is not a realistic expectation. Likewise, if 12:30 pm is when you watch the news, you will create a conflict in your current routine by scheduling a new activity at the same time. The logistics surrounding a new behavior must support its implementation.

Craving: Make It Attractive

For your cravings to lead to action, the possible reward must be attractive. Cravings involve the sensations of wanting—the anticipation of pleasure—and liking—the experience of pleasure. Both sensations trigger the production of dopamine in the brain, or the chemical involved in desire, but 90% of dopamine production is dedicated to wanting. The anticipation of something outweighs the pleasure of receiving that thing.

  • Think about how much more excited you are before a date than when on the date. If it’s a first date, you anticipate making a connection, which excites you. If, when you’re on the date, you have a good time but don’t feel a strong connection, you won’t want to continue dating that person.
  • However, if you feel a connection, you will crave a second date because you desire to feel that connection again. It’s the promise of continued connection that keeps you motivated to date this person.

If anticipation is the greatest craving, you must create more promise for the rewards your actions lead to. There are two ways that rewards can be heightened to create stronger desires.

Heightened Rewards

Temptation bundling is one way to make any behavior more attractive. Like habit stacking, use the end of a new behavior as a cue for something that excites you. This helps make the new behavior more enticing.

  • You’ve set up the end of lunch as a cue to walk for 20 minutes, but you don’t feel driven to walk because you’d rather play video games. If playing video games for 20 minutes becomes the reward for walking, you’ll begin to crave the walk so you can claim your reward afterward.
  • The formula is: After X [current habit], I will do Y [new habit]. After I do Y, I get to do Z [craved habit].”

Redefining your behaviors can also make them more appealing. Rather than thinking about having to walk 20 minutes a day, change the perspective to getting to walk 20 minutes a day. This small change in perspective highlights the positive elements of walking. You begin to see how fortunate you are to have the ability to walk and the time in your day to do so. When you feel gratitude for the activities you’re able to participate in, you’ll be more driven to keep participating.

Response: Make It Easy

You will only follow through on behaviors that are easy to perform and require little effort. That is simply human nature. Therefore, to stay motivated, make behavior as effortless as possible.

But making behaviors easy doesn’t mean only doing easy things. The idea is to make it easy for you to keep showing up for the behavior you want to perform. By simply showing up, you maintain your desired identity, which gives you pride and confidence to keep making progress.

Making Behaviors Easier

Reducing the effort of an action means removing the friction existing between you and the behavior. The more friction there is, the less likely you are to act.

  • If you want to eat a healthier breakfast, remove friction by setting out the items required before bed.
  • If you want to read more before bed, place a book on your pillow after waking up each morning.

The two-minute rule is also effective in making behaviors easier. Often, you jump into the biggest changes required when trying to build new habits or start new behaviors. But big changes in behavior are hard to maintain over time. You will make more progress if you break the behavior down into tiny two-minute increments. These increments will build into massive achievements.

  • You want to start jogging and decide to jog for 20 minutes each day after work. You are successful for a few days, but on the fourth day, you’re too tired, so you skip it. Suddenly, the behavior has stopped.
  • However, you likely have enough energy to lay out your running clothes, and it only takes two minutes. Or better yet, you’ve laid out running clothes before leaving for work to reduce friction. The next step is to put them on. The next step after that is to put on your shoes. Then, leave the house. Then, walk to the sidewalk. Each of these two-minute actions connect to get you to the point of being ready to run. The obstacles to overcome are small compared with the overwhelming idea of running for 20 minutes.
  • Some days, you may only get as far as changing into the clothes, but that small act is still a vote cast for your identity as a jogger and is still considered a victory.

Small successes motivate you to achieve others. Commit to two-minute actions at a time, and it will be easier to perform each required step until you have achieved the full habit.

Reward: Make It Satisfying

If the end result of your efforts is unenjoyable, why would you want to do them again? You wouldn’t, which is why rewards need to be satisfying for habits to form.

Many rewards you receive are delayed. You only receive a paycheck after weeks of work. You only get a final grade after months of studying. But human nature is wired to want instant gratification, and most good behaviors need time before the positive results accumulate. You sacrifice now to benefit later. To stay motivated to continue good habits, find ways to create rewards that are instantly satisfying.

Adding Instant Gratification to Rewards

Reinforcements are good motivators for continued action. You remember the end of behavior more than any other part. Therefore, make the end of your behavior rewarding with a reinforcement to motivate continued action.

  • You won’t notice a major difference in your savings account after a week if you deposit one dollar a day. The reward of more financial freedom is too far down the road to elicit immediate pleasure. But the act of saving a dollar a day can be rewarding with a small reinforcement. Each time you deposit a dollar into your savings, give yourself an hour of relaxation, a cookie, or an extra 30 minutes of television. You’ll feel motivated to keep saving if you end the action with something gratifying.
  • Whatever the reinforcement is, it must be satisfying and instantly received.

Habit tracking can also make behaviors more rewarding. Create visual representations of your progress by marking a day on a calendar, transferring pebbles from one jar to another, or keeping a journal log of your completed actions. When you can visually see your accomplishments, you’ll be motivated to continue acting.

The act of tracking can feel rewarding in and of itself. It is satisfying to mark each successful completion of an action in some way. The pleasure experienced through that act becomes a cue to want to feel that satisfaction again.

Only track one major habit at a time to avoid becoming overwhelmed by the act.

Breaking Bad Habits

You likely have habits you wish you didn’t. To break bad habits, invert the laws from positive to negative in the following way:

  1. Cue—Make it invisible.
  2. Craving—Make it unattractive.
  3. Response—Make it difficult.
  4. Reward—Make it unsatisfying.

Finding the Right Habits

The habits you gravitate toward and are able to maintain are influenced by your genetic make-up, predispositions, and natural talents. Choose behaviors that highlight your strengths and interests—they’ll be more enjoyable and easier to stick with.

The Big 5 Personality Traits

To figure out which behaviors are optimal for you, learn which personality traits you possess.

There are 5 personality traits, each with a spectrum of behavior that highlights who you are. All five are rooted in biology and typically remain unchanged throughout your life.

  1. Openness to experience—from curious and daring to cautious and unvarying.
  2. Conscientiousness—from organized and methodical to spontaneous and relaxed.
  3. Extroversion—from sociable and gregarious to reclusive and reticent.
  4. Agreeableness—from affable and caring to difficult and withdrawn.
  5. Neuroticism—from fretful and sensitive to assured and resilient.

Your personality doesn’t dictate which behaviors you’re capable of performing. However, your personality does suggest which behaviors you will most likely be successful with.

  • A less agreeable person will struggle to build a habit of forming one social connection a week or sending out greeting cards.
  • An extrovert will have a harder time staying off of social media than an introvert.
  • Someone who is conscientious will have more success creating better working habits.

There is a version of each habit and behavior that falls along your spectrum of personality. Choose the version that fits your natural personality, not the ones that friends, family, or society deem best.

  • Your friend lost weight by working out at a gym. But you hate crowds, so taking daily walks or hiking works better for you.
  • Your mother saved money by removing lattes and takeout from her daily routine. But you enjoy lattes and don’t cook, so putting 10% of your paycheck in a savings account works better for you.

Stick to what works for you to experience the greatest success.

Continuing to Show Up

Boredom is inevitable with any repeated activity; therefore, there will be a point in which your excitement and motivation for a new behavior wanes. When this happens, it is easy to abandon good behaviors that are still working to find behaviors that are novel and exciting. To curb this harmful instinct, keep behaviors exciting by following the Goldilocks Rule, building on momentum, and crafting a flexible identity.

The Goldilocks Rule

The brain loves a challenge, but only when that challenge is within your capabilities. If the challenge is too easy, you lose interest. If it’s too hard, you become frustrated or disheartened. A challenge that is just right keeps you engaged and motivated to improve. This is the essence of the Goldilocks Rule, also referred to as just manageable difficulty.

There is a balance required between increasing the difficulty of a task just enough to stay interesting and keeping the level of difficulty at a point where success can still be attained. The just manageable difficulty meter sits at the edge of your current abilities. When each attempt to act includes a 50/50 chance of success, you will continue to work hard because you crave the satisfaction of succeeding.

Building on Momentum

Another reason you lose motivation is that you’ve reached the habit line of your current behavior, or the point where the action becomes automated. If you stop there, you will stop growing and lose motivation. You may think you’re making progress because you’re putting in the reps, but all you’re doing is reinforcing the same behavior. If your actions don’t change, your results won’t change.

Reaching a goal requires momentum within your system. Once a habit becomes automated, build on it with 1% improvements to keep behaviors novel and progress continuous.

Crafting a Flexible Identity

Your identity is made up of various characteristics. Your identity is not simply the general label given to those characteristics, such as “CEO” or “vegan.” When identity hinges on one label, it becomes brittle. When you lose it, you lose yourself and motivation.

  • If you identify as a CEO and lose your job, who are you now?
  • If you label yourself vegan and have to start eating animal protein for your health, what is your new identity?

The solution is to think of yourself in terms of the associated characteristics to avoid losing your identity if that label changes. When you identify with positive characteristics, rather than one positive label, your identity is flexible.

  • “I’m a CEO” becomes “I’m someone who is smart, innovative, and a strong leader.” You can still be those things in a new position.
  • “I’m a vegan” becomes “I’m someone who is conscientious about what I eat and consumes foods that are healthy for me and the earth.” You can still have positive eating habits regardless of your dietary requirements.

With a flexible identity, you continue casting votes for who you are regardless of the circumstances. A flexible identity goes with the flow of life. A brittle identity fights against it.

Reflection

Habit formation is not a one-time occurrence. Your brain is constantly scanning your environment for cues and ways to automate behavior. Therefore, you need to continually check in with your identity and behaviors to ensure they’re still working for you.

Reflect on your habits and progress, and look for areas that promote growth and areas that require refinement. The more small adjustments in behavior you make, the more likely you will end up on the path of your choosing. You can become anyone you want and reach any goal you want to reach if you work hard and remain aware of the life you’re leading.
