Our most commonly held formula for success is broken. But recent discoveries in the field of positive psychology have shown that this formula is actually backward: Happiness fuels success, not the other way around. This isn't just an empty mantra. This discovery has been repeatedly borne out by rigorous research in psychology and neuroscience, management studies, and the bottom lines of organizations around the globe. In The Happiness Advantage, Shawn Achor, who spent over a decade living, researching, and lecturing at Harvard University, draws on his own research--including one of the largest studies of happiness and potential at Harvard and others at companies like UBS and KPMG--to fix this broken formula. It's about how to reap the benefits of a happier and more positive mind-set to achieve the extraordinary in our work and in our lives.
