Robert A. Heinlein

An armed society is a polite society. Manners are good when one may have to back up his acts with his life.

Everything is theoretically impossible, until it is done.

Never underestimate the power of human stupidity.

Women and cats will do as they please, and men and dogs should relax and get used to the idea.

I never learned from a man who agreed with me.

A competent and self-confident person is incapable of jealousy in anything. Jealousy is invariably a symptom of neurotic insecurity.

May you live as long as you wish and love as long as you live.
