David DeSteno is a professor of psychology at Northeastern University, where he directs the Social Emotions Group. He is a fellow of the Association for Psychological Science and the American Psychological Association, for which he serves as editor-in-chief of the journal Emotion.
His book, "Emotional Success" provides an accessible and powerful path to grit: our prosocial emotions. These feelings – gratitude, compassion and pride – are easier to generate than the willpower and self-denial that underpin traditional approaches to grit. And, while willpower is quickly depleted, prosocial emotions actually become stronger the more we use them. These emotions have another crucial advantage: they’re contagious.
