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.
EpictetusRemember that you are but an actor, acting whatever part the Master has ordained. It may be short or it may be long. If he wishes you to represent a poor man, do so heartily; if a cripple, or a magistrate, or a private man, in each case act your part with honor.
Epictetus
