How can you change your life? In Atomic Habits, James Clear argues that the key lies in your habits: the automatic behaviors that make up more than half of what you do every day. Clear contends that implementing the right habits will drastically improve your life—but to do so, you must understand how habits work and how to change yours.

In this guide, you’ll discover why habits matter and the three mindsets you can use to create them. You’ll then learn how habits form and the four keys to changing yours. Finally, you’ll learn how to continue improving habits you've implemented. Along the way, we’ll examine how other psychologists and experts approach habit formation, and we’ll explore how Clear’s theories either align with or differ from theirs.
