People today are still living off the table scraps of the '60s. They are still being passed around - the music and the ideas.

Take up an idea, devote yourself to it, struggle on in patience, and the sun will rise for you.

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

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

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

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.
