Charles Duhigg 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.

The result is a compelling argument and an empowering discovery: the key to exercising regularly, losing weight, raising exceptional children, becoming more productive or even building revolutionary companies is understanding how habits work. By harnessing this new science, we can transform our businesses, our communities, and our lives.
