Do every act of your life as though it were the very last ac... - Marcus Aurelius, Meditations

"The first rule is to keep an untroubled spirit. The second is to look things in the face and know them for what they are."

"If someone is able to show me that what I think or do is not right, I will happily change, for I seek the truth, by which no one was ever truly harmed. It is the person who continues in his self-deception and ignorance who is harmed."

"If someone can prove me wrong and show me my mistake in any thought or action, I shall gladly change. I seek the truth, which never harmed anyone: the harm is to persist in one's own self-deception and ignorance."

"We must make haste then, not only because we are daily nearer to death, but also because the conception of things and the understanding of them cease first."

"You are a little soul carrying about a corpse, as Epictetus used to say."
