young people are ambivalent about adulthood. As Arnett argues, they want the security and stability adulthood brings, but they don’t want to settle into a daily grind. They don’t want to limit their spontaneity or put limits on their dreams.

Recovering from suffering is not like recovering from a disease. Many people don’t come out healed; they come out different.

What’s the difference? Happiness involves a victory for the self, an expansion of self. Happiness comes as we move toward our goals, when things go our way. You get a big promotion. You graduate from college. Your team wins the Super Bowl. You have a delicious meal. Happiness often has to do with some success, some new ability, or some heightened sensual pleasure. Joy tends to involve some transcendence of self. It’s when the skin barrier between you and some other person or entity fades away and you feel fused together. Joy is present when mother and baby are gazing adoringly into each other’s eyes, when a hiker is overwhelmed by beauty in the woods and feels at one with nature, when a gaggle of friends are dancing deliriously in unison. Joy often involves self-forgetting. Happiness is what we aim for on the first mountain. Joy is a by-product of living on the second mountain.
