Summary of Atomic Habits

Core Idea

Tiny changes compound into remarkable results: 1% daily improvement = 37x better in one year; tiny habits are the building blocks of mastery
Systems matter more than goals: Focus on the process and daily habits, not the outcome—goals are momentary, systems are permanent
Identity drives behavior: Change who you are, not just what you do—habits reinforce identity, identity reinforces habits

Use implementation intentions: Write "I will [BEHAVIOR] at [TIME] in [LOCATION]" to remove ambiguity
Stack habits: Pair new habits with existing ones ("After I pour coffee, I will meditate")
Design your environment: Make good habits visible, bad habits invisible; put gym shoes by the door, hide junk food
Track what you do: Keep a Habits Scorecard to notice which behaviors are actually happening

Use temptation bundling: Pair something you need to do with something you want to do (Netflix only while exercising)
Join a culture where the habit is normal: Surround yourself with people already doing what you want to do
Reframe habits positively: Change "I have to run" to "I get to build endurance"—pleasure drives repetition

Reduce friction: Eliminate steps between you and good habits; reduce effort through environment design
Master the Two-Minute Rule: Start with a version so small it takes under 2 minutes (one page, one push-up, one meditation breath)
Prime your environment: Lay out gym clothes the night before; prep healthy food on Sundays
Automate what you can: Use timers, apps, password resets, or one-time purchases to remove willpower from the equation

Immediate rewards matter most: Our brains prefer instant gratification—make good habits feel good now
Track your progress visually: Use a calendar X's, habit tracker, or jar of marbles—watching progress builds motivation
Never miss twice: One slip is human; two slips start a new bad habit—recover immediately
Use accountability partners: Public commitment and witness make consequences real and motivating

Make it invisible: Remove cues (phone in another room, hide snacks, unplug the TV)
Make it unattractive: Highlight costs; reframe to see downsides clearly
Make it difficult: Increase friction (unsubscribe from notifications, add extra steps between you and temptation)
Make it unsatisfying: Create accountability; face consequences immediately (habit contracts, public pledges)

Genes don't determine destiny, they show opportunities: Pick the game that favors your natural strengths; combine skills to reduce competition
The Goldilocks Rule: Stay motivated by working on challenges just beyond your current ability—not too easy, not impossible
Habits are about identity, not just outcomes: Every rep casts a "vote" for who you want to become; identity compounds over time
Reflection prevents complacency: Review monthly/yearly to ensure habits still serve you; update identity as circumstances change

This week: Create a Habits Scorecard—list daily behaviors and mark each good (+), bad (−), or neutral (=)
Pick one habit: Write an implementation intention ("After [current habit], I will [new habit]") or use the Two-Minute Rule version
Design the environment: Remove one friction point for a good habit; add one friction point for a bad habit
Track visually: Use a calendar, app, or jar to see your streak—make progress obvious
Find your tribe or accountability partner: Join a community or tell someone your commitment; social pressure compounds behavior change
