In The Power of Regret, Pink draws on research in psychology, neuroscience, economics and biology to challenge widely-held assumptions about emotions and behaviour. Using the largest sampling of attitudes about regret ever conducted from his own World Regret Survey - which has collected regrets from more than 16,000 people in 105 countries - he identifies the four core regrets that most people have. These four regrets, Pink argues, operate as a 'photographic negative' of the good life. By understanding what people regret the most, we can understand what they value the most. And by following the simple, science-based, three-step process that he sets out, we can transform our regrets in a positive force for working smarter and living better.
