Predicting rain doesn't count. Building arks does.

You can be sure that over the next 10 years, you'll see something that you did not think was possible.

The only question is whether you're going to do it today or tomorrow. If you keep saying you're going to do it tomorrow, you'll never do it. You have to get on it today.

Forethought we may have, undoubtedly, but not foresight.

Nothing comes from doing nothing.

I have far more respect for the person with a single idea who gets there than for the person with a thousand ideas who does nothing.
