"Willpower has gone from being the thing that distinguishes us humans from other animals to the thing that distinguishes us from each other. We may all have been born with the capacity for willpower, but some of us use it more than others. People who have better control of their attention, emotions, and actions are better off almost any way you look at it. They are happier and healthier. Their relationships are more satisfying and last longer. They make more money and go further in their careers. They are better able to manage stress, deal with conflict, and overcome adversity. They even live longer. When pit against other virtues, willpower comes out on top. Self-control is a better predictor of academic success than intelligence (take that, SATs)"
