The virtue as the art consecrates itself constantly to what's difficult to do, and the harder the task, the shinier the success.
AristotleAnd inasmuch as the great-souled man deserves most, he must be the best of men; for the better a man is the more he deserves, and he that is best deserves most. Therefore the truly great-souled man must be a good man. Indeed greatness in each of the virtues would seem to go with greatness of soul.
Aristotle
