Epicurus — "The man who says that all things are not possible to him is a fool."

"Do not spoil what you have by desiring what you have not; remember that what you now have was once among the things you only hoped for."

"We should not believe in fate, but in our own free will."

"The man who says that all things happen of necessity cannot criticize one who says that not all things happen of necessity. For he admits that the very statement he is making is made of necessity."

"The wise man will not groan and howl when he is tortured."

"Death is nothing to us, since when we are, death has not come, and when death has come, we are not."
