Opportunity beckons more surely when misfortune comes upon a person than it ever does when that person is riding the crest of a wave of success. It sharpens a person's wits, if that person will let it, enabling him or her to see more clearly and evaluate situations with a more knowledgeable judgment.
EpictetusWhen your thoughts, words, and deeds form a seamless fabric, you streamline your efforts and thus eliminate worry and dread.
EpictetusKnow you not that a good man does nothing for appearance sake, but for the sake of having done right?
EpictetusDon't just say you have read books. Show that through them you have learned to think better, to be a more discriminating and reflective person. Books are the training weights of the mind. They are very helpful, but it would be a bad mistake to suppose that one has made progress simply by having internalized their contents." Translation by Sharon Lebell
