A new idea comes suddenly and in a rather intuitive way. But intuition is nothing but the outcome of earlier intellectual experience.

An idea is something that won't work unless you do.

To have a great idea, have a lot of them.

The man with a new idea is a Crank until the idea succeeds.

Nothing comes from doing nothing.

No idea is so outlandish that it should not be considered with a searching but at the same time a steady eye.
