When you let go of your attention for a little while, do not think you may recover it whenever you please.
EpictetusWe must ever bear in mind --that apart from the will there is nothing good or bad, and that we must not try to anticipate or to direct events, but merely to accept them with intelligence.
EpictetusIf you do not wish to be prone to anger, do not feed the habit; give it nothing which may tend to its increase. At first, keep quiet and count the days when you were not angry: "I used to be angry every day, then every other day: next, every two, then every three days!" and if you succeed in passing thirty days, sacrifice to the gods in thanksgiving.
