“An immensely rewarding book, filled with ingenious research, wise advice, and insightful reflections on the human condition.”

“Willpower (the thing) lies at the curious intersection of science and behavior. Willpower (the book) lies at the intersection of Roy Baumeister, an extraordinarily creative scientist, and John Tierney, a phenomenally perceptive journalist. Ignore it at your peril.”

“Who knew that a book about such a daunting topic could be as wonderfully entertaining as it is enlightening! Tierney and Baumeister have produced a highly intelligent work full of fascinating information (and great advice) about a core element of modern living. Bravo.”

“Deep and provocative analysis of people’s battle with temptation and masterful insights into understanding willpower: why we have it, why we don’t, and how to build it. A terrific read.”

“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, told by the scientist who made it happen and the journalist who made it news.”
