John Tierney has written a number of books. The book ‘Willpower’, he wrote in partnership with psychologist Roy Baumeister, who is also a professor at the University of Florida. John is foremost a journalist who writes for The New York Times and The City Journal. John and I tackle the empirical underpinnings of willpower. We discuss case studies and experiments that have been conducted on the subject. We go on to talk about the power laws of willpower and the ways to improve one's willpower… and of course, how to recognize it in others.
