It depends upon

“A man is not much if he can’t depend on himself, and nothing if others can’t depend on him.”

~  Benjamin Black

There’s a school of psychology which holds that happiness is subjective. Good or bad things happen in life, but people return to the same base level of happiness. Researchers found evidence that people adapt completely to marriage, divorce, widowhood, birth of a child, and layoffs.

Death of a spouse, for instance, is a terrible event characterized by a radical drop in happiness, but in the year that follows happiness rises, and within two years happiness returns to normal and may even rise above the baseline (as the subject gets caught in another hedonic cycle). A similar hedonic pattern follows most negative events—and positive ones too. People get over them. In almost every unhappy situation that people are faced with, the happiness level reverts to the baseline. 

Because people have the strength to eventually rebound after any tragedy, they can depend on themselves, and others can depend on them to get them through the difficult times in life. Choose to be a happy person no matter what happens in your life and people will know they can depend on you. It just depends on you.
