When people tell me they've learned from experience, I tell them the trick is to learn from other people's experience.

It's good to learn from your mistakes. It's better to learn from other people's mistakes.

The world is not composed of heroes and villains, but of men and women with all the passions that God has given them. The ignorant condemn, but the wise pity.

Fools multiply when wise men are silent.

The man who is truly wise knows that he knows very little.

The tongue of a fool is the key of his counsel, which, in a wise man, wisdom hath in keeping.
