Teach yourself

The feeling of happiness is given to everyone as a representative of the human species.

By the life journey, the feeling of happiness is deformed, or even completely destroyed (I will skip now how and why).

A person LEARNS lack of happiness.

Normally, this feeling is constantly in the body along with respiration and pulse.

If it happened that there is no such feeling of happiness, you need to RE-LEARN yourself back to normal.
