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.
EpictetusWatch yourself as you go about your daily business and later reflect on what you saw, trying to identify the sources of distress in your life and thinking about how to avoid that distress.
