“To every man is given the key to the gates of heaven. The same key opens the gates of hell.

And so it is with science.”
― Richard Feynman

“Difficulty shows what men are. Therefore when a difficulty falls upon you, remember that God, like a trainer of wrestlers, has matched you with a rough young man. Why? So that you may become an Olympic conqueror; but it is not accomplished without sweat.”
― Epictetus, Epictetus. The Discourses as Reported By Arrian. Vol. I. Books 1 and 2. With an English Translation By W. A. Oldfather

“Withdraw into yourself and look. And if you do not find yourself beautiful yet, act as does the creator of a statue that is to be made beautiful: he cuts away here, he smoothes there, he makes this line lighter, this other purer, until a lovely face has grown upon his work. So do you also: cut away all that is excessive, straighten all that is crooked, bring light to all that is overcast, labour to make all one glow of beauty and never cease chiselling your statue, until there shall shine out on you from it the godlike splendour of virtue, until you shall see the perfect goodness surely established in the stainless shrine.”
― Plotinus

“I never saw a wild thing sorry for itself. A small bird will drop frozen dead from a bough without ever having felt sorry for itself.”
