The difference between genius and stupidity is; genius has its limits.

Anyone can make them cry, but it takes a genius to make them laugh.

Towering genius disdains a beaten path. It seeks regions hitherto unexplored.

Even the genius asks questions.

I used to think I must be a genius, but nobody's noticed. I used to wonder whether I'm a genius or I'm not, which is it? I used to think, well, I can't be mad, because nobody's put me away, therefore, I'm a genius. A genius is a form of madness, and we're all that way, you know, and I used to be a bit coy about it, like my guitar playing.

There is no genius where there is not simplicity.
