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.

To get a great idea, come up with lots of them.

If you have a really good idea, stick to it, but be flexible on how you get there. Be stubborn on your vision but flexible on the details... People who are right a lot change their mind... They have the same data set that they had at the beginning, but they wake up, and they re-analyze things all the time, and they come to a new conclusion, and then they change their mind.

It's perfectly healthy-encouraged, even to have an idea tomorrow that contradicted your idea today.

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

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