I put the sweat of my life into this project, and if it’s a failure, I’ll leave the country and never come back.

I’m not a paranoid deranged millionaire.

A million dollars isn’t what it used to be.

We don’t have a monopoly. Anyone who wants to dig a well without a Hughes bit can always use a pick and shovel.

Every man has his price, or a guy like me couldn’t exist.

If I have made a mistake in the design, then I’m the one who should pay for it. I certainly would not ask somebody else to fly a plane if I were afraid to do it myself.

Money can’t buy happiness.

Do the impossible, because almost everyone has told me my ideas are merely fantasies.

Passion will make you crazy, but is there any other way to live?
