A pioneering psychologist reveals how three powerful emotions are the surest path to attaining your goals. Grit, the ability to persevere against all odds, is widely recognized as the key to success. But how can grit be cultivated and sustained? In this myth-shattering book, David DeSteno reveals that the most powerful tools we can draw upon to achieve our toughest goals are not willpower or self-denial, but our prosocial emotions—gratitude, compassion, and pride. In fact, this undervalued toolkit evolved specifically to help us resist immediate temptations in favor of long-term gains. DeSteno breaks down the long-overlooked mechanisms of perseverance built into our brains and shows how we can work with our emotions, instead of denying them, to achieve our goals. And he shows how we can do it with greater ease and deeper satisfaction than we would have thought possible.
