|Epictetus (AD 55|
"Make the best of what is in your power, and take the rest as it happens."
"People are disturbed not by things, but by the views which they take of them."
"A wise man is he who does not grieve for the thing which he has not, but rejoices for those which he has."
"If you would cure anger, do not feed it. Say to yourself: 'I used to be angry every day; then every other day; now only every third or fourth day.' When you reach thirty days offer a sacrifice of thanksgiving to the gods."
