Discourses and Selected Writings, Epictetus

"In life our first job is this, to divide and distinguish things into two categories: externals I cannot control, but the choices I make with regard to them I do control."

"The chief thing to remember is that the door is open. Don't be a greater coward than children, who are ready to announce, 'I won't play any more.' Say, 'I won't play any more,' when you grow weary of the game, and be done with it. But if you stay, don't carp."

"When happiness is come by fairly, others are happy for us too."

"The learning process is boring to anyone completely new to, and unfamiliar with, a skill."

"In our school, we picture the philosopher's will in line with events, so that nothing happens contrary to our wishes and, conversely, nothing fails to happen what we want to happen."

"Reading should serve the goal if attaining peace; if it doesn't make you peaceful, what good is it?"

"True peace is characterized by nothing so much as steadiness and imperturbability."

"'Isn't reading a kind of preparation for life?'

But life is composed of things other than books. It is as if an athlete, on entering the stadium, where to complain that he's not outside exercising."

"Settle on the type of person you want to be and stick to it, whether alone or in company."

"Finally decide that you are an adult who is going to devote the rest of your life to making progress."

"...the Olympics have started."
