There is nothing that we can properly call our own but our time, and yet everybody fools us out of it who has a mind to do it. If a man borrows a paltry sum of money, there must needs be bonds and securities, and every common civility is presently charged upon account. But he who has my time thinks he owes me nothing for it, though it be a debt that gratitude itself can never repay.

Let him that hath done the good office conceal it; let him that received it disclose it.

Do what you should, not what you may.

Do you desire not to be angry? Be not inquisitive. He who inquires what is said of him only works out his own misery.

While you teach, you learn.

One crime has to be concealed by another.

Happy is the man who can endure the highest and lowest fortune. He who has endured such vicissitudes with equanimity has deprived misfortune of its power.
