The rule

Happiness often follows a U-shaped curve throughout a person's life.

A person's happiness tends to be high in youth, dip in middle age, and rise again in older age. This pattern is a normal part of human experience.

A person's happiness often follows a predictable pattern. Happiness is usually high when a person is young. It tends to decrease during middle age. Then, happiness often increases again as a person gets older. This pattern is called the 'U-bend of happiness'. It shows that feeling less happy in middle age is a common experience. It is not a sign of personal failure. This understanding can give a person hope. It suggests that happiness will likely increase again.

A manager feels less happy in their 40s than in their 20s. The manager learns about the U-bend of happiness. This knowledge helps the manager understand that this feeling is normal. The manager realizes that happiness often improves with age. This understanding reduces the manager's worry.
