Almost all new ideas have a certain aspect of foolishness when they are first produced.

The vitality of thought is in adventure. Ideas won't keep. Something must be done about them. When the idea is new, its custodians have fervor, live for it, and if need be, die for it.

If your idea is big enough, and crazy enough, all you have to do is survive. If you survive, you will succeed.
