The Story of James Clear

  • On the final day of his sophomore year, James was hit in the face with a baseball bat between the eyes.
  • He suffered a broken nose, multiple skull fractures, and two broken eye sockets.
  • He went into a coma.
  • Six years after that incident, he was selected the top male athlete at Denison University and named to the ESPN Academic All-American Team.
  • His injury taught him 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.


What is the Power of Habits?

The effects of small habits compound over time. If you can get 1% better each day for a year, you’ll end up 37 times better at the end of the year.

Unfortunately, the slow speed of transformation makes it easy for us to give up and slide into a bad habit.

Remember: success is a product of daily habits – not an overnight transformation.

But habits can be a double-edged sword. Bad habits can chop you down just as quickly as good habits build you up. Hence understanding the details is critical.

Remember: Mastery requires patience.

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

Focusing on the system rather than a single goal is the core theme of this book and also the underlying meaning of the word atomic.

What are the 4 steps to building life-long habits?

Habits reduce cognitive load and free up mental capacity, so you can allocate your attention to other tasks. It’s only by making the fundamentals of life easier to create the mental space needed for free-thinking and creativity.


  1. Cue is the bit of information that triggers your brain to initiate a behavior predicting a reward.
  2. Cravings are the motivational forces behind every habit.
  3. The response is the actual habit you perform, which can be thought or action.
  4. Rewards are the end goal of out habit.

This book's backbone is the 4-step model of habits-cue, craving, response reward-and the four laws of behavior change that evolve out of these steps.


The 1st Law of Behavior Change – Make it obvious

Use techniques like pointing and calling or a habit scorecard.

Pointing and calling is literally that, and the Japanese use it in their railway system to reduce errors by 85 percent.

A habit scorecard is about creating a list of your daily habits, from when you wake up to the time to fall back to sleep in the night. Then rate ‘+’ or ‘-‘ based on whether if it is a good or bad habit. Mark ‘=’ is it is a neutral habit.

These processes help generate awareness of our habits and acknowledge the cues that trigger them, making it possible to respond in a way that benefits us.

Start new habits with implementation intention. When X happens, I will perform Y.

Habit stacking is another technique to overhaul your habits. After the current habit, I will make a new habit.


Design your surroundings or environment for success. A cue triggers every habit, make the cue stand out, so we notice it. The context becomes the cue.

Make cues of good habits obvious and cues to bad habits invisible.


The 2nd Law of Behavior Change – Make it attractive.

The more attractive an opportunity, the more likely it is to be habit-forming.

Use temptation bundling to make habits attractive. The strategy is to pair an action you want to do with an action you need to do.

Our cultures determine our attractions. We tend to adopt a habit that receives praise and approval from our family, friends, and ideals. Join a culture where your desired behavior is the norm.

Habits are attractive when we associate them with a positive feeling and unattractive when we associate them with a negative feeling.


The 3rd Law of Behavior Change – Make it easy

The most effective form of learning is practice, not planning.

The amount of time you have been performing a habit is not as significant as the number of times you have performed it.

Law of least effort: Create an environment where doing the right thing is as easy as possible. Increase the friction associated with bad behavior.

Two-minute rule: When starting a new habit, it should take less than two minutes. The point is a new good habit should not feel like a challenge.

The more you ritualize the beginning of the process, the more likely it becomes that you can slip into the state of deep focus required to do things.

Standardize before you optimize.



The 4th Law of Behavior Change – Make it satisfying.

The Cardinal Rule of Behavior change – what is immediately rewarded is repeated. What is immediately punished is avoided.

Humans give immediate reward a priority over delayed rewards, hence the rule.

The first three laws help you create a good habit. The fourth law ensures you repeat it.

The paper clip strategy - Visual measures to keep progress satisfying. Track your habits to make them obvious, easy, attractive and satisfying.

Use the habit stacking + habit tracking formula.

To recover from a lost habit – never miss twice. Don’t put up a zero. Don’t break the chain. Rebound quickly. Reclaim fast. Don’t spiral into repeated mistakes. Keep your habit streak running.

A habit contract can be used to add a social cost to any behavior. It makes the cost of breaking your promises public and painful.



How to stay motivated in life and work?

Build habits that work for your personality. Habits are easier when they align with your natural abilities.

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

You have to fall in love with boredom. Be endlessly fascinated by doing the same things over and over.

Habits + Deliberate Practice = Mastery.

Reflection and review are critical to behavior change as they create identity. Reflection and review is a process that allows you to remain conscious of your performance over time.



Conclusion - Is there a Secret to Long-Lasting results?

Yes. Never stop making improvements. Small habits, they don’t add up. They compound. That’s the power of atomic habits.

Tiny changes. Remarkable results.
