An atomic habit is a regular practice or routine that is not only small and easy to do but is also the source of incredible power; a component of the system of compound growth.

Bad habits repeat themselves again and again not because you don’t want to change, but because you have the wrong system for change.

Changes that seem small and unimportant at first will compound into remarkable results if you’re willing to stick with them for years.

Five Big Ideas:

1. Habits are the compound interest of self-improvement.
2. If you want better results, then forget about setting goals. Focus on your system instead.
3. The most effective way to change your habits is to focus not on what you want to achieve, but on who you wish to become.
4. The Four Laws of Behavior Change are a simple set of rules we can use to build better habits. They are
   1. make it obvious,
   2. make it attractive,
   3. make it easy, and
   4. make it satisfying.
5. The environment is the invisible hand that shapes human behavior.

“Any habit can be broken down into a feedback loop that involves four steps: cue, craving, response, and reward.”

Small actions build up over time. So changing or eliminating habits can lead to success.

“Getting 1 percent better every day counts for a lot in the long-run.”

If you want to make the cue habit-forming, you have to make it obvious and put it in a place in which you will see it.

To avoid temptation, block those things that distract you.

Write down the queue to start a new habit into small chunks. If you want to write, tell yourself that you will write three sentences every day.
