Harvard psychologist Dan Gilbert explains the fallacy behind the notion that to achieve happiness, one must get what they want. He uses psychology and neuroscience to explain that what we think makes us happy is, oftentimes, completely wrong.
As Gilbert explains it, 'Natural happiness is what we get when we get what we wanted, and synthetic happiness is what we make when we don't get what we wanted. In our society, we have a strong belief that synthetic happiness is of an inferior kind.'
