Keep your attention focused entirely on what is truly your own concern, and be clear that what belongs to others is their business and none of yours.
EpictetusAsk yourself, "How are my thoughts, words and deeds affecting my friends, my spouse, my neighbour, my child, my employer, my subordinates, my fellow citizens?"
EpictetusWhy, do you not know, then, that the origin of all human evils, and of baseness, and cowardice, is not death, but rather the fear of death?
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
