In 'The Power of Habit,' business reporter Charles Duhigg takes us to the edge of scientific discoveries that explain why habits exist and how they can be changed. Along the way we learn why some people and companies struggle to change, despite years of trying, while others seem to remake themselves overnight. We visit laboratories where neuroscientists explore how habits work and where, exactly, they reside in our brains. We discover 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. We go inside Procter & Gamble, Target superstores, Rick Warren Saddleback Church, NFL locker rooms, and the nation largest hospitals and see how implementing so-called keystone habits can earn billions and mean the difference between failure and success, life and death. At its core, 'The Power of Habit' contains one argument: The key to exercising regularly, losing weight, raising exceptional children, becoming more productive, building revolutionary companies and social movements, and achieving success is understanding how habits work.
