Marcus Aurelius: “Consider that everything is opinion, and opinion is in thy power.”

He was also easy in conversation, and he made himself agreeable without any offensive affectation.

All these things happen to them by reason of their ignorance of what is good and evil.

Throw away thy books; no longer distract thyself: it is not allowed; but as if thou wast now dying, despise the flesh; it is blood and bones and network, a contexture of nerves, veins, and arteries.

Begin the morning by saying to thyself, I shall meet with the busybody, the ungrateful, arrogant, deceitful, envious, unsocial.
