Most companies and schools follow this formula: if you work harder, you will be more successful, and then you will be happy. This formula is scientifically backward. A decade of research shows that training your brain to be positive at work first actually fuels greater success second. In fact, 75% of our job success is predicted not by intelligence, but by your optimism, social support network and the ability to manage energy and stress in a positive way. By researching top performers at Harvard, the world’s largest banks, and Fortune 500 companies, Shawn Achor discovered patterns that create a happiness advantage for positive outliers — the highest performers at the company. Based on his book, The Happiness Advantage (September 2010 from Random House), Shawn explains what positive psychology is, how much we can change, and practical applications for reaping the Happiness Advantage in the midst of change and challenge.
