The Power of Regret: How Looking Backward Moves Us Forward by Daniel H. Pink argues that regret is a universal and valuable emotion, not something to be ignored, and that understanding our regrets can help us live better lives. Drawing on extensive research and his "World Regret Survey," Pink identifies four core regrets—foundation, boldness, moral, and connection—and provides a three-step process to transform them into a force for future progress, helping us make smarter decisions and find greater meaning.
