I used to think happiness was genetic, that happy people were born that way. That’s only half-true; some research suggests that 50% is determined by heredity. What about the other half? About 10% comes from living conditions. The remaining 40% depends on YOU.
Happiness is not just the absence of sadness. It’s related to optimism, hope, pleasure, and joy, but it’s not interchangeable with any of them. It’s difficult to quantify, to measure, and to track. And it’s something that most people say they want. Even the U.S. Declaration of Independence included the pursuit of happiness as an inalienable right.
