It requires creative problem solving, and many unhappy people don’t want to work that hard, even to improve their own lives. They want someone else—their bosses, their spouses, their parents, the government—to figure out what would make them happy, prepare it for them, and serve it to them nicely browned, with an apple in its mouth. I’ve known people who spend their whole lives in a state of furious self-pity because this never happens for them.
