Retire into thyself. The rational principle which rules has this nature, that it is content with itself when it does what is just, and so secures tranquility.

In the end, what would you gain from everlasting remembrance? Absolutely nothing. So what is left worth living for? This alone: justice in thought, goodness in action, speech that cannot deceive, and a disposition glad of whatever comes, welcoming it as necessary, as familiar, as flowing from the same source and fountain as yourself.

Without a purpose, nothing should be done.

Always run to the short way; and the short way is the natural: accordingly say and do everything in conformity with the soundest reason. For such a purpose frees a man from trouble, and warfare, and all artifice and ostentatious display.

When you are offended at anyone's fault, turn to yourself and study your own failings. By attending to them, you will forget your anger and learn to live wisely.

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.

Reject your sense of injury, and the injury itself disappears.
