Why do we tend to remember the best or worst moment of an experience, as well as the last moment, and forget the rest? Why do we feel most comfortable when things are certain, but feel most alive when they're not? And why are our most cherished memories clustered into a brief period during our youth? The New York Times bestselling authors of Switch and Made to Stick explore why certain brief experiences can jolt us and elevate us and change us--and how we can learn to create such extraordinary moments in our life and work.
