Since the beginning of his career, social psychologist Roy Baumeister has conducted many experimental observations. He found that many couples eventually break up because they continually fought over trivial issues. Many husbands and wives have also experienced this problem. It seemed that merely being together would cause them to fight. Some people even reported trying to find a place to have a drink after work or socialize with friends, in order to arrive home late and avoid any further conflicts.

In spite of this, Baumeister advised them to go home early after work. Some people were confused: why give couples more time to fight with each other? Baumeister didn’t see it this way. His research showed that many people were exhausting their willpower at work, and they had none left to deal with their partners’ demands and annoying habits when they got home. So when their partner said something they didn’t like or asked for something, the other person often responded in a mean, sarcastic manner, thus turning the situation into a bitter quarrel.

Baumeister suggested that people go home early, that is, when they still have enough energy or willpower. Only with a certain amount of willpower can you deal with family affairs. Our willpower, like an account balance, is a fixed value, which requires us to spend our wealth of willpower as wisely as we manage our finances. The book Willpower: Rediscovering the Greatest Human Strength is a practical willpower training manual. This book will tell you how to maintain your willpower and help you become a focused, self-disciplined, and efficient person.

Since its publication, the book Willpower: Rediscovering the Greatest Human Strength has been highly praised by many scholars and best-selling authors. Daniel Todd Gilbert, author of Stumbling on Happiness, commented that, “Willpower is sinfully delicious. Once you start reading, you won't be able to stop. A fascinating account of the exciting new science of self-control.” David Allen, author of Getting Things Done, praised the book by saying, “Tierney and Baumeister have produced a highly intelligent work full of fascinating information (and great advice) about a core element of modern living. Bravo!”
