If someone irritates you, it is only your own response that is irritating you. Therefore, when anyone seems to be provoking you, remember that it is only your judgment of the incident that provokes you. -
EpictetusIt is the act of an ill-instructed man to blame others for his own bad condition; it is the act of one who has begun to be instructed, to lay the blame on himself; and of one whose instruction is completed, neither to blame another, nor himself.
