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.
EpictetusWherever I go it will be well with me, for it was well with me here, not on account of the place, but of my judgments which I shall carry away with me, for no one can deprive me of these; on the contrary, they alone are my property, and cannot be taken away, and to possess them suffices me wherever I am or whatever I do.
Epictetus
