To the wise, life is a problem; to the fool, a solution.

Ambition means tying your well-being to what other people say or do. Self-indulgence means tying it to the things that happen to you. Sanity means tying it to your own actions.

If thou workest at that which is before thee ... expecting nothing, fearing nothing, but satisfied with thy present activity according to Nature, and with heroic truth in every word and sound which thou utterest, thou wilt live happy. And there is no man who is able to prevent this.

The only thing that isn't worthless: to live this life out truthfully and rightly, And be patience with those who don't.

A man is a little soul carrying around a courpse.

Dwell on the beauty of life. Watch the stars, and see yourself running with them.

Infinity is a fathomless gulf, into which all things vanish.
