I find out what the world needs. Then I go ahead and try to invent it.

I try not to invent things that people don't need.

Everyone steals in commerce and industry. I've stolen a lot, myself. But I know how to steal! They don't know how to steal!

My principal business is giving commercial value to the brilliant - but misdirected - ideas of others.

I make more mistakes than anyone else I know, and sooner or later, I patent most of them.

I never did anything by accident, nor did any of my inventions come by accident; they came by work.
