The quality of life does not depend on happiness alone, but also on what one does to be happy. If one fails to develop goals that give meaning to one’s existence, if one does not use the mind to its fullest, then good feelings fulfill just a fraction of the potential we possess….Without dreams, without risks, only a trivial semblance of living can be achieved.

Excerpt from Finding Flow by Mihály Csíkszentmihályi.
