Everybody has regrets, Daniel H. Pink explains in "The Power of Regret" (Riverhead Books). They’re a universal and healthy part of being human. And understanding how regret works can help us make smarter decisions, perform better at work and school, and bring greater meaning to our lives. Drawing on research in social psychology, neuroscience, and biology, Pink debunks the myth of the “no regrets” philosophy of life. Using the largest sampling of American attitudes about regret ever conducted as well as his own World Regret Survey — which has collected regrets from more than 15,000 people in 105 countries — he lays out the four core regrets that each of us has. These deep regrets offer compelling insights into how we live and how we can find a better path forward.
