Can you resist everything except temptation? In a hedonistic age full of distractions, it's hard to possess willpower - or in fact even understand why we should need it. Yet it's actually the most important factor in achieving success and a happy life, shown to be more significant than money, looks, background or intelligence. This book reveals the secrets of self-control. Here Roy Baumeister, one of the world's most esteemed and influential psychologists, and journalist John Tierney, turn this notion on its head. They show us that willpower is like a muscle that can be strengthened with practice and improved over time. The latest laboratory work shows that self-control has a physical basis to it and so is dramatically affected by simple things such as eating and sleeping - to the extent that a life-changing decision may go in different directions depending on whether it's made before or after lunch. Based on years of psychological research and filled with practical advice, this book will teach you how to gain from self-control without pain, and discover the very real power in willpower. The results are nothing short of life-changing.
