writer Jean Stafford scoffed, “Happy people don’t need to have fun,” but in fact, studies show that the absence of feeling bad isn’t enough to make you happy; you must strive to find sources of feeling good. One way to feel good is to make time for play—which researchers define as an activity that’s very satisfying, has no economic significance, doesn’t create social harm, and doesn’t necessarily lead to praise or recognition. Research shows that regularly having fun is a key factor in having a happy life; people who have fun are twenty times as likely to feel happy.
