If you hear that someone is speaking ill of you, instead of trying to defend yourself you should say: 'He obviously does not know me very well, since there are so many other faults he could have mentioned.'
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.
EpictetusIf we are not stupid or insincere when we say that the good or ill of man lies within his own will, and that all beside is nothing to us, why are we still troubled?
