If you do not wish to be prone to anger, do not feed the habit; give it nothing which may tend to its increase.
EpictetusDo nothing in a depressed mood, nor as one afflicted, nor as thinking that you are in misery, for no one compels you to that.
EpictetusSome things are up to us [eph' hรชmin] and some things are not up to us. Our opinions are up to us, and our impulses, desires, aversionsโin short, whatever is our own doing. Our bodies are not up to us, nor are our possessions, our reputations, or our public offices, or, that is, whatever is not our own doing.
