It is easy to perform a good action, but not easy to acquire a settled habit of performing such actions.
AristotleThe good man is he for whom, because he is virtuous, the things that are absolutely good are good; it is also plain that his use of these goods must be virtuous and in the absolute sense good.
AristotleMoral excellence comes about as a result of habit. We become just by doing just acts, temperate by doing temperate acts, brave by doing brave acts.
Aristotle
