Say you want to start going to the gym or practicing a musical instrument. How long should it take before you stop having to force it and start doing it automatically?

The surprising answers are found in Making Habits, Breaking Habits, a leading psychologist's popular examination of one of the most powerful and underappreciated processes in the brain. Although people like to think that they are in control, the vast majority of human behavior occurs without any decision-making or conscious thought.

Drawing on hundreds of fascinating studies, psychologist Jeremy Dean busts the myths to finally explain why seemingly easy habits, like eating an apple a day, can be surprisingly difficult to form, and how to take charge of your brain's natural "autopilot" to make any change stick.

Witty and intriguing, Making Habits, Breaking Habits shows how behavior occurs more than just a product of what you think. It is possible to bend your habits to your will—and be happier, more creative, and more productive.
