Chapter 1: The Surprising Power of Atomic Habits

  • Small daily improvements matter more than waiting for a big moment.
  • We often think big success needs big actions, like losing weight or achieving goals.
  • Getting just 1 percent better each day may not seem big, but it adds up over time.
  • The math shows that being 1 percent better daily for a year makes you much better in the end.
  • Small wins and setbacks become something much more significant over time.
  • Habits, like compound interest, become more powerful as you repeat them.


1% worse every day for one year. 0.99 365 = 00.03

1% better every day for one year. 1.01 365 = 37.78

Chapter 2: How Your Habits Shape Your Identity (and Vice Versa)


  • Changing Outcomes: This is the first layer and focuses on changing your results, like losing weight or achieving specific goals.
  • Changing Process: The second layer involves changing habits and systems, such as adopting a new gym routine or organizing your workspace for better productivity.
  • Changing Identity: The deepest layer involves changing your beliefs and worldview, including your self-image and judgments about yourself and others

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.

The goal is not to run a marathon, the goal is to become a runner.

The goal is not to learn an instrument, the goal is to become a musician.

The most practical way to change who you are is to change what you do.

Each time you write a page, you are a writer.

Each time you practice the violin, you are a musician.

Each time you start a workout, you are an athlete.

Each time you encourage your employees, you are a leader.

Each habit not only gets results but also teaches you something far more important: to trust yourself. You start to believe you can accomplish these things.

Chapter 3: How to Build Better Habits in 4 Simple Steps

The process of building a habit can be divided into

Four simple steps: cue, craving, response, and reward.

  • Habit Building Process:
  • Cue: A trigger that predicts a reward and initiates a behavior.
  • Craving: The motivational force behind every habit, driven by the desire for a state change.
  • Response: The actual habit performed, is influenced by motivation and friction associated with the behavior.
  • Reward: The end goal of every habit, serving the purposes of satisfaction and teaching.

For example,

  • Cue: Noticing a buzzing phone with a new text message.
  • Craving: Wanting to learn the contents of the message.
  • Response: Grabbing the phone and reading the text.
  • Reward: Satisfying the craving to read the message, associating grabbing the phone with a buzzing sound.


  • The Four Laws of Behavior Change:
    • How to Create a Good Habit:
      • 1st law (Cue): Make it obvious.
      • 2nd law (Craving): Make it attractive.
      • 3rd law (Response): Make it easy.
      • 4th law (Reward): Make it satisfying.
    • Inversion for Breaking Bad Habits:
      • 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.
  • Questions for Behavior Change:
    • Whenever you want to change your behavior, 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?

Chapter 4: THE 1ST LAW Make It Obvious ( The Man Who Didn’t Look Right)

  • Challenges in Habit Change:
  • Maintaining awareness of our actions is a big challenge in changing habits.
  • Consequences of bad habits often sneak up on us.
  • The “Point-and-Call” System:
  • The Habits Scorecard is like a “point-and-call” system for personal lives.
  • It’s a simple exercise to increase awareness of our behavior.
  • Creating Your Habits Scorecard:
  • Make a list of your daily habits.
  • Examples: Wake up, check your phone, make tea, etc.
  • Labeling Your Habits:
  • Look at each behavior and decide if it’s good, bad, or neutral.
  • Use “+” for good habits, “–” for bad habits, and “=” for neutral habits.
  • Sample Habits Scorecard:
  • Wake up = (neutral)
  • Check my phone – (bad)
  • Make a cup of tea + (good)
  • Personalized Evaluation:
  • Marks depend on your situation and goals.
  • This exercise helps us clearly see our habits and decide which ones to keep or change.

Chapter 5: The Best Way to Start a New Habit

  • Clarity Over Motivation:
    • Often, people think they lack motivation when the real issue is a lack of clarity in knowing when and where to take action.
    • Waiting for the perfect time to make improvements can lead to a lifetime of inaction.
  • Implementation Intentions:
    • Setting implementation intentions eliminates the need to wait for inspiration.
    • Questions like whether to write a chapter or meditate become irrelevant when you have a predetermined plan.
  • Simple Habit Stacking:
    • To form new habits, fill in the sentence: “I will [BEHAVIOR] at [TIME] in [LOCATION].”
    • For example, “I will meditate for one minute at 7 a.m. in my kitchen.”
  • Hope and Fresh Starts:
    • Starting a new habit on the first day of the week, month, or year increases the likelihood of action due to heightened hope.
    • Hope serves as motivation for taking action, and a fresh start is inherently motivating.

In building new habits, leveraging the connectedness of behavior is effective.

Habit stacking, a form of implementation intention, involves pairing a new habit with a current habit. Created by BJ Fogg, this method establishes an obvious cue for almost any habit by following the formula: “After [CURRENT HABIT], I will [NEW HABIT].”

For instance, “After I pour my cup of coffee each morning, I will meditate for one minute.”

The key is to tie your desired behavior into something you already do daily, allowing you to create larger stacks by chaining small habits together and benefit from the natural momentum that follows.

Chapter-wise summary: THE MOUNTAIN IS YOU

Chapter 6: Motivation Is Overrated; Environment Often Matters More

  • Power of Vision:
  • Vision is the most potent human sensory ability, with about 10 million of our 11 million sensory receptors dedicated to sight.
  • Roughly half of the brain’s resources are utilized for vision, making visual cues a significant catalyst for our behavior.
  • Designing Your Environment:
  • Small changes in what you see can lead to significant shifts in what you do.
  • Living and working in environments filled with productive cues and devoid of unproductive ones is crucial.
  • Taking Control of Your Environment:
  • You can design your environment for success rather than being a victim of it.
  • Make cues for preferred habits more obvious to increase the likelihood of consistent behavior.
  • Redesigning for Habits:
  • If you want a habit to be a big part of your life, make the cue a big part of your environment.
  • For example, placing a pill bottle by the faucet to remember medication or keeping a guitar in the living room for more frequent practice.
  • Environment Design and Control:
  • Environment design is powerful because it influences how we engage with the world.
  • Many people live in environments created by others, but you can take back control by altering your spaces.
  • New Habits, New Contexts:
  • Associating a new habit with a new context is easier than building it in the face of competing cues.
  • Stepping outside your normal environment helps form new habits without the interruptions of old cues.

Chapter 7: The Secret to Self-Control

  • Bad Habits Feed Themselves:
  • Bad habits make you feel bad, and in trying to numb those feelings, they perpetuate themselves.
  • For example, feeling sluggish leads to more TV watching, creating a cycle of bad habits.
  • Why Just Saying “No” Doesn’t Work:
  • Resisting temptation is hard and drains your energy quickly.
  • Long-term success in good habits is tough in a bad environment.
  • Stop Bad Habits at the Root:
  • A better way is to stop bad habits by avoiding what triggers them.
  • Simple steps like leaving your phone in another room or unfollowing social media accounts can make a big difference.
  • Make Habits Invisible:
  • Instead of making habits obvious, make them invisible to break the cycle.
  • Small changes, like removing a cue, can surprisingly make the whole habit fade away.
  • Short-Term vs. Long-Term Control:
  • Trying to control yourself in the moment is hard.
  • It’s better to set up your environment to support good habits without relying on willpower.
  • The Real Trick to Control:
  • To control yourself better, make it easy to see good habits and hard to notice bad ones.
  • It’s about making your surroundings help you do what you want to do.

Chapter 8: THE 2ND LAW Make It Attractive (How to Make a Habit Irresistible)

  • Dopamine and Habits:
  • Habits work like a dopamine-driven loop, whether it’s playing video games or having a meal.
  • Dopamine rises not just during pleasure but also in anticipation of it, boosting motivation.
  • Anticipating Rewards:
  • Your brain releases dopamine when you predict pleasure, even before the reward.
  • This anticipation boosts your motivation to act on a behavior.
  • Temptation Bundling:
  • Attractive behaviors become more appealing when combined with less exciting ones.
  • For instance, read gossip magazines only at the gym or get a pedicure while processing emails.
  • Premack’s Principle in Action:
  • Premack’s Principle says more probable behaviors reinforce less probable ones.
  • Condition yourself to do less appealing tasks by pairing them with something enjoyable.
  • Combining Strategies:
  • Use habit stacking and temptation bundling together for a powerful combo.
  • Create rules to guide your behavior: After a necessary habit, follow it with something you enjoy.
  • Practical Examples:
  • Want to read the news but need to express gratitude?
    • After coffee, express gratitude; then, read the news.
  • Want to watch sports but need to make sales calls?
    • After lunch, make calls; then, check ESPN.

These strategies tap into the power of anticipation and pairing habits, making positive behaviors more motivating.

Chapter 9: The Role of Family and Friends in Shaping Your Habits.

  • Imitating Habits:
  • According to the author, our earliest habits aren’t choices; we imitate them from friends, family, and society.
  • Social norms from various cultures and groups shape our behavior, often without conscious thought.
  • The Power of Social Influence:
  • Social norms act as invisible rules guiding our daily actions, influencing everything from marriage to spending habits.
  • Many times, we follow these habits without questioning or remembering them.
  • Influence of Close Relationships:
  • We imitate habits from those closest to us, copying how parents handle arguments or how peers interact.
  • Proximity increases the likelihood of adopting habits from someone.
  • Guidance from the Many:
  • When unsure how to act, we look to the group for guidance, checking reviews or imitating common behaviors.
  • The group’s normal behavior often outweighs an individual’s desired behavior.
  • Internal Pressure to Conform:
  • There’s internal pressure to comply with group norms, even if it means sacrificing personal preferences.
  • Being accepted by the group often holds more reward than individual achievements.
  • Imitating the Powerful:
  • Humans seek power, prestige, and status, evident in titles, recognition, and achievements.
  • Pursuing power historically provided more resources, lower survival concerns, and increased attractiveness.

In summary, our habits are shaped by imitation from close relationships, societal norms, and the pursuit of power and status. Social influence plays a significant role in our daily behaviors.

Chapter 10: How to Find and Fix the Causes of Your Bad Habits

  • Cravings and What’s Really Going On:
  • Every action you want to do has a top-level desire and a deeper reason behind it.
  • For instance, if you really crave tacos, the root cause is your body needing food and water for survival.
  • Hidden Reasons Behind Our Actions:
  • The deeper reasons include saving energy, getting food and water, finding love, connecting with others, fitting in socially, easing uncertainty, and gaining status.
  • When you crave something specific, like tacos, it’s just a way your deeper needs show up.
  • How Our Brain Evolved:
  • Our brains didn’t evolve to want certain habits like smoking or checking social media.
  • Instead, these habits latch onto our basic needs, like reducing stress, seeking approval, or wanting recognition.
  • Examples of Needs and Habits:
  • Finding love and connecting = using Tinder.
  • Bonding with others = scrolling through Facebook.
  • Seeking approval = sharing on Instagram.
  • Easing uncertainty = searching on Google.
  • Gaining status = playing video games.
  • Different Ways to Solve the Same Problem:
  • There are many ways to address the same need; habits are just the ones you learn.
  • One person might smoke to relieve stress, while another might run. It’s about what you’ve learned to do.
  • Linking Solutions to Problems:
  • Your habits are solutions linked to specific issues.
  • Once a solution, like smoking or running, is connected to a problem, it becomes a habit you go back to.

Chapter: 11 THE 3RD LAW Make It Easy (Walk Slowly, but Never Backward)

  • Motion vs. Action:
  • Being in motion is about planning, strategizing, and learning.
  • Action is the behavior that brings actual results.
  • While motion is helpful, it alone doesn’t produce outcomes.
  • Examples of Motion vs. Action:
  • Motion: Outlining ideas for articles.
  • Action: Sitting down and writing an article.
  • Motion: Searching for a better diet plan.
  • Action: Actually eating a healthy meal.
  • Outcome Through Action:
  • No matter how much you plan or talk about it, only the action of working out will get you in shape.
  • Action is what delivers the desired results.

Chapter 12: The Law of Least Effort

  • Law of Least Effort:
  • Humans naturally choose the option that requires the least effort.
  • Opting for the easier choice is a part of conserving energy.
  • Value for Least Effort:
  • Realized actions are the ones that provide the most value with the least effort.
  • We are inclined to do what is easy.
  • Energy and Habits:
  • Every action demands a certain amount of energy.
  • Habits with lower energy requirements are more likely to occur.
  • Friction and Stronger Self:
  • On tough days, reducing friction helps your stronger self emerge.
  • Making things easier increases the likelihood of overcoming challenges.
  • Make It Easy for Long-Term Payoff:
  • The goal is to make long-term payoff activities as easy as possible.
  • Simplify your environment for easy access to beneficial habits.

Chapter 13: How to Stop Procrastinating by Using the Two-Minute Rule

Habit Influence:
Did you know nearly half of your daily actions are habitual? It’s not just about the actions themselves; habits also shape the conscious decisions that follow.

Two-Minute Rule:
Keep it simple. The Two-Minute Rule suggests that when starting a new habit, it should take less than two minutes to do. Break down any habit into a two-minute version for an easy start.

Scaling Down Habits:
Trim down your habits to two minutes or less:

  • “Read before bed” becomes “Read one page.”
  • “Do thirty minutes of yoga” becomes “Take out my yoga mat.”
  • “Study for class” becomes “Open my notes.”
  • “Fold the laundry” becomes “Fold one pair of socks.”
  • “Run three miles” becomes “Tie my running shoes.”

Gateway Habit:
Make the first two minutes a breeze. A new habit should be easy to kickstart, creating a gateway to more productive actions.

Chapter 14: How to Make Good Habits Inevitable and Bad Habits Impossible

Making Habits Hard:

  • Success involves making bad habits hard, an inversion of the “make it difficult” approach.
  • Utilize commitment devices, present choices controlling future actions, binding you to good habits, and restricting bad ones.
  • Victor Hugo’s commitment device was shutting away clothes to focus on writing.
  • Tasks should require more effort to abandon good habits than to start them, increasing friction to make bad habits impractical.

Breaking Bad Habits:

  • Make bad habits impractical by increasing friction, following the “make it difficult” principle.
  • Automated ethical behavior, like the cash register, makes stealing practically impossible.
  • Implement commitment devices for bad habits, locking in future behavior.
  • One-time actions can secure good habits, such as nutrition, sleep, productivity, happiness, general health, and finance.

Automated Good Habits:

  • Leverage technology to automate and simplify good habits, transforming hard actions into easy behaviors.
  • The technology ensures reliable and effective adherence to the right behavior.
  • Examples include email filters, turning off notifications, setting up automatic savings plans, and cutting cable service.
  • The most practical and efficient way to guarantee the right behavior is through technological automation.

Chapter 15: THE 4TH LAW Make It Satisfying (The Cardinal Rule of Behavior Change)

  • Choosing Now Over Later: Our brains like things that make us happy right away, even if it’s not good for us in the long run. We might do something enjoyable now, like smoking or overeating, even if it causes problems later.
  • Bad Habits’ Instant Pleasure: Bad habits give us immediate happiness but have delayed bad consequences. Smoking feels good now but might harm our health later. It’s like enjoying something today but paying the price tomorrow.
  • Good Habits and Future Gains: On the other hand, good habits may not be fun at first, like exercising, but they bring good things in the future. It’s like putting in some effort now to feel better and healthier down the road.

Chapter 16: How to Stick with Good Habits Every Day.

  • Satisfaction in Progress: Observing progress is satisfying and habit trackers, like calendars or logs, offer tangible evidence of your efforts, enhancing the positive feeling of moving forward.
  • Immediate Satisfaction: Habit trackers provide instant gratification by visually showcasing your consistency. Crossing off completed tasks or marking a streak creates a sense of accomplishment right away.
  • Obvious and Attractive: Habit tracking is obvious in its visual cues, such as a chain of completed actions on a calendar, making it easy to notice and be reminded to continue. The visual representation makes it attractive and motivating.
  • Progress as Motivation: Progress is a powerful motivator. Each small win recorded in a habit tracker becomes an added motivation, encouraging you to persist in your positive behaviors.
  • Inherent Satisfaction: The act of tracking itself becomes a rewarding experience. Whether it’s ticking off completed tasks or adding entries to a log, the satisfaction derived from tracking boosts motivation.
  • Encourages Consistency: The visual cues created by habit trackers serve as reminders to maintain consistency. Research shows that people who track their progress are more likely to improve in various goals.
  • Building Momentum: Habit tracking can create a positive feedback loop, where each recorded success builds momentum. The additive effect of small wins fuels your desire to continue and reinforces the habit loop.

Chapter 17: How an Accountability Partner Can Change Everything

  • Instant Displeasure: The inverted 4th Law suggests making behaviors immediately unsatisfying. The concept revolves around associating instant discomfort with undesirable actions.
  • Pain as a Teacher: Painful consequences act as effective teachers. Immediate and significant costs for mistakes or bad habits expedite the learning process, ensuring rapid correction.
  • Creating Accountability: Introducing immediate costs, such as the disapproval of an accountability partner, taps into the human concern for others’ opinions. This adds a social dimension, making inaction more costly and undesirable.

Chapter 18: The Truth About Talent (When Genes Matter and When They Don’t)

  • Genetic Influence: Genes are like a helpful guide or a tricky obstacle course, depending on the situation. They don’t decide everything, just point out where you might shine. Choosing tasks that suit you aligns your goals with what you’re naturally good at.
  • Choosing the Right Stuff: It’s like picking activities that make you go, “Hey, I’m pretty good at this!” Genes give hints, but you’re not stuck. Match your interests with what you’re good at, and that’s where the magic happens.
  • Questions to Find the Fun: Ask yourself:
  • What feels fun but seems like work to others?
  • When do I get so into something that I forget time?
  • Where do I do better than most people?
  • What comes naturally to me without caring about what others think?
  • When do I feel most alive and true to myself?
  • Flow and Feeling Good: Doing things that make you forget the world around you is like hitting the sweet spot. Find tasks where you shine more than others, and follow what feels like you being your awesome self.

Chapter 19: The Goldilocks Rule: How to Stay Motivated in Life and Work

  • Boredom Can Ruin Habits: Doing the same thing over and over can get boring. When habits become dull, we often quit and look for something new, even if the old habits were working fine.
  • Avoiding the Temptation of Something New: When we feel less excited, we tend to search for new, exciting things. But sticking to a habit means facing days when you don’t feel like it.
  • Pro vs. Not-so-Pro Thinking: Pros stick to the plan, even on dull days. They know what’s important and stay on track. Amateurs let life’s problems pull them away. Getting really good at something means finding joy in doing it over and over.

Chapter 20: The Downside of Creating Good Habits.

  • Becoming Good: To be great at something, you need habits and practice to make skills automatic.
  • Like Learning Basketball: Imagine practicing easy things in basketball first, like dribbling, before moving on to fancier moves. It’s the same with habits.
  • Keep Improving: Once you’re good at one thing, don’t stop. Work on more habits. Think about what went well and what you learned regularly.
  • Yearly Reflection Questions:
    1. Successes: What went well?
    2. Challenges: What didn’t go so well?
    3. Learnings: What did I learn?
  • Habits and Change: While habits bring many benefits, they can also keep us stuck in old ways. Regular reflection helps ensure our habits align with our evolving needs in a changing world.
