Do every act of your life as if it were your last.

I am an old man and have had many worries, but most have never come to pass.

At day's first light have in readiness, against disinclination to leave your bed, the thought that "I am rising for the work of man."

Look back over the past, with its changing empires that rose and fell, and you can foresee the future, too.

It is a sin to persue pleasure as a good and to avoid pain as a evil.

Live not as though there were a thousand years ahead of you. Fate is at your elbow; make yourself good while life and power are still yours.

As far as you can, get into the habit of asking yourself in relation to any action taken by another: "What is his point of reference here?" But begin with yourself: examine yourself first.
