Everything may happen.

Some pretend want of power to make a competent return; and you shall find in others a kind of graceless modesty, that makes a man ashamed of requiting an obligation, because it is a confession that he has received one.

Cling tooth and nail to the following rule: Not to give in to adversity, never to trust prosperity, and always to take full note of fortune's habit of behaving just as she pleases, treating her as if she were actually going to do everything it is in her power to do. Whatever you have been expecting for some time comes as less of a shock.

Only a great man, believe me, and one whose excellence rises far above human failings, will not allow anything to be stolen from his own span of time, and his life is very long precisely because he has devoted to himself entirely any time that became available. None of it lay uncultivated and idle, none was under another man's control, for guarding it most jealously, he found nothing worth exchanging for his own precious time.

Be wary of the man who urges an action in which he himself incurs no risk.

Life without the courage for death is slavery.

Every guilty person is his own hangman.
