The pioneer scientist must have "a vivid intuitive imagination, for new ideas are not generated by deduction, but by artistically creative imagination."

"The place to find is within yourself."

The only people for me are the mad ones, the ones who are mad to live, mad to talk, mad to be saved, desirous of everything at the same time, the ones who never yawn or say a commonplace thing, but burn, burn, burn, like fabulous yellow roman candles exploding like spiders across the stars and in the middle you see the blue centerlight pop and everybody goes "Awww!"

The mind is but a barren soil; a soil which is soon exhausted, and will produce no crop, or only one, unless it be continually fertilized and enriched with foreign matter. 

Don't be afraid to fail.  Be afraid not to try.

If there wasn't any competition, I'd be very worried, because it would mean we were not doing very well.
