People think that when you want to change your life, you need to think big. But world-renowned habits expert James Clear has discovered another way. He knows that real change comes from the compound effect of hundreds of small decisions: doing two push-ups a day, waking up five minutes early, or holding a single short phone call.

In The Power of Habit, award-winning journalist Charles Duhigg takes us into the thrilling and surprising world of the scientific study of habits.He examines why some people and companies struggle to change, despite years of trying, while others seem to remake themselves overnight. He visits laboratories where neuroscientists explore how habits work and where, exactly, they reside in our brains. And he uncovers how the right habits were crucial to the success of Olympic swimmer Michael Phelps, Starbucks CEO Howard Schultz, and civil-rights hero Martin Luther King, Jr.
