The true measure of a man is how he treats someone who can do him absolutely no good.

Sex: the expense is damnable, the position is ridiculous, and the pleasure fleeting.

I am an old man and have known a great many troubles, but most of them never happened.

Mark Twain1835–1910

If you hold a cat by the tail you learn things you cannot learn any other way.

Mark Twain1835–1910

Experience is not what happens to a man; it is what a man does with what happens to him.
