“Most people assume the following formula: If you work hard, you will become successful, and once you become successful, then you’ll be happy. Success first, happiness second. The only problem is that this formula is broken. The formula is broken because it is backward. More than a decade of groundbreaking research in the fields of positive psychology and neuroscience has proven in no uncertain terms that the relationship between success and happiness works the other way around. Happiness and optimism actually fuel performance and achievement.”
