If one fails to develop goals that give meaning to one's existence, if one does not use the mind to it's fullest, then good feelings fulfill just a fraction of the potential we possess. True happiness involves the pursuit of worthy goals. Without dreams, without risks, only a trivial semblance of living can be achieved.
