Sickness is a hindrance to the body, but not to your ability to choose, unless that is your choice. Lameness is a hindrance to the leg, but not to your ability to choose. Say this to yourself with regard to everything that happens, then you will see such obstacles as hindrances to something else, but not to yourself.
EpictetusWhen we act pugnaciously, and injuriously, and angrily, and rudely, to what level have we degenerated? To the level of the wild beasts. Well, the fact is that some of us are wild beasts of a larger size, while others are little animals, malignant and petty.
EpictetusIf 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.
