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.

If at first the idea is not absurd, then there is no hope for it.

Take up one idea. Make that one idea your life - think of it, dream of it, live on that idea. Let the brain, muscles, nerves, every part of your body, be full of that idea, and just leave every other idea alone. This is the way to success.

Nothing comes from doing nothing.
