Happiness is the positive feeling you get from a walk in nature or tasty dessert. It’s definitely a good thing. But satisfaction runs deeper. It’s the sense of meaning and accomplishment that comes from a life well lived. At the end of the day, most people value satisfaction more.

Keeping our mood up with exercise, adequate sleep, and social engagement is a fine idea. But research shows the best way to muscle through tough times is by finding meaning in our struggles.

Chasing meaning is more likely to lift our spirits and make us tougher than any effort to cheer ourself up.
