Atomic Habits provides a step-by-step plan for building better habits for a lifetime by making tiny improvements over time.

These tiny improvements may seem insignificant when they are implemented but result in big changes over time.

The author opens this book with the gripping account of being struck in the face with a baseball bat in high school, his slow recovery and his revelation and dramatic change in his life due to the tiny habits he discovered.

James Clear bases his observations and recommendations on the fields of biology, neuroscience, psychology and more.

One of the key concepts in the book is the idea of the Habit Loop.  All habits proceed through these four stages in the same order forming a loop.

The authors set up the entire premise of the book with a description of a scene from the movie “City Slickers.”

In one scene, Curly asks Mitch if he knows what the secret of life is.  Mitch answers no.  Curly then holds up one finger and says the secret to life is one thing, just one thing.

From this quote and through a process of discovery, the authors narrowed down their focus to this one question, “What’s the ONE Thing you can do this week such that by doing it everything else would be easier or unnecessary?”

The Domino Effect is the concept that domino falls can topple big things.  A domino can knock over a domino 50% larger.  In that scenario, the 57^th domino is almost the distance to the moon.  The moon is reachable if you prioritize everything and put all of your energy into accomplishing the most important thing.
