Why did Paul Gauguin abandon middle-class life to follow the path of a starving artist? What explains the massive success of Steve Jobs, a man with great ideas but weak programming skills and a questionable managerial style? How did Dean Karnazes—the famed "Ultramarathon Man"—transform himself from a directionless desk jockey into an extreme athlete who once ran fifty marathons in fifty days? As the renowned emotion researcher Jessica Tracy reveals in Pride, each of these superachievers has been motivated by an often maligned emotion: pride. Its dark, hubristic side is well known, but Tracy shows that pride is also essential for helping us become our best, brightest selves. It makes us strive for excellence. In the right doses and the right contexts, it has been proven to boost creativity, motivate altruism, and confer power and prestige on those who display it. Avoiding the bad kind of pride while nurturing the good kind, Tracy argues, might just be the secret to success.
