Our most commonly held formula for success is broken. Conventional wisdom holds that if we work hard we will be more successful, and if we are more successful, then we’ll be happy. If we can just find that great job, win that next promotion, lose those five pounds, happiness will follow. 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. When we are positive, our brains become more engaged, creative, motivated, energetic, resilient, and productive at work.
