If any be unhappy, let him remember that he is unhappy by reason of himself alone. For God hath made all men to enjoy felicity and constancy of good.
EpictetusOther people's views and troubles can be contagious. Don't sabotage yourself by unwittingly adopting negative, unproductive attitudes through your associations with others.
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.
