When therefore we are hindered, or disturbed, or grieved, let us never attribute it to others, but to ourselves; that is, to our own principles. An uninstructed person will lay the fault of his own bad condition upon others. Someone just starting instruction will lay the fault on himself. Some who is perfectly instructed will place blame neither on others nor on himself.
EpictetusIf you wish to live a life free from sorrow, think of what is going to happen as if it had already happened.
EpictetusIf 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. -
EpictetusIf you set your heart upon philosophy, you must straightway prepare yourself to be laughed at and mocked by many who will say Behold a philosopher arisen among us! or How came you by that brow of scorn? But do you cherish no scorn, but hold to those things which seem to you the best, as one set by God in that place. Remember too, that if you abide in those ways, those who first mocked you, the same shall afterwards reverence you; but if you yield to them, you will be laughed at twice as much as before.
