If you wish to live a life free from sorrow, think of what is going to happen as if it had already happened.
EpictetusDoes a man reproach thee for being proud or ill-natured, envious or conceited, ignorant or detracting? Consider with thyself whether his reproaches are true. If they are not, consider that thou art not the person whom he reproaches, but that he reviles an imaginary being, and perhaps loves what thou really art, though he hates what thou appearest to be.
EpictetusWhen you are offended at any man's fault, turn to yourself and study your own failings. Then you will forget your anger.
Epictetus
