The hardest part of gaining any new idea is sweeping out the false idea occupying that niche.

A human being should be able to change a diaper, plan an invasion, butcher a hog, conn a ship, design a building, write a sonnet, balance accounts, build a wall, set a bone, comfort the dying, take orders, give orders, cooperate, act alone, solve equations, analyze a new problem, pitch manure, program a computer, cook a tasty meal, fight efficiently, die gallantly.

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.

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