“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.”
― Epictetus

“Never esteem anything as of advantage to you that will make you break your word or lose your self-respect.”
― Marcus Aurelius, Meditations

“If you are distressed by anything external, the pain is not due to the thing itself, but to your estimate of it; and this you have the power to revoke at any moment.”
― Marcus Aurelius, Meditations

“First say to yourself what you would be;
and then do what you have to do.”
― Epictetus
