Common and vulgar people ascribe all ills that they feel to others; people of little wisdom ascribe to themselves; people of much wisdom, to no one.
EpictetusAttach yourself to what is spiritually superior, regardless of what other people think or do. Hold to your true aspirations no matter what is going on around you.
EpictetusIn life our first job is this, to divide and distinguish things into two categories: externals I cannot control, but the choices I make with regard to them I do control. Where will I find good and bad? In me, in my choices.
EpictetusYou can be invincible, if you enter into no contest in which it is not in your power to conquer.
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.
