What's the best way to build self-control, patience, productivity, and delayed marshmallow eating? For decades psychologists and economists have told us to develop traits like willpower and grit. But psychologist David DeSteno describes a better, easier, and more effective path--the emotions. We talk to David about his new (not-self-help) book "Emotional Success," which argues that the emotions of gratitude, pride, and compassion can help us fulfill long-term goals and (as a special bonus) make us happier and better people.Plus, David and Tamler take a quiz that measures how utilitarian they are, and you won't believe the results!!! (Actually, you will.)
