When our friends are present we ought to treat them well; and when they are absent, to speak of them well.
EpictetusConsider first the nature of the business in hand; then examine thy own nature, whether thou hast strength to undertake it.
EpictetusHappiness and freedom begin with a clear understanding of one principle: Some things are within our control, and some things are not. It is only after you have faced up to this fundamental rule and learned to distinguish between what you can and can't control that inner tranquility and outer effectiveness become possible.
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
