If you would know a man, observe how he treats a cat.

Never frighten a little man. He'll kill you.

When one teaches, two learn.

I've found out why people laugh. They laugh because it hurts... because it's the only thing that'll make it stop hurting.

Human beings hardly ever learn from the experience of others. They learn; when they do, which isn't often, on their own, the hard way.

To get anywhere, or even live a long time, a man has to guess, and guess right, over and over again, without enough data for a logical answer.
