The greatest invention in the world is the mind of a child.

I think death is the most wonderful invention of life. It purges the system of these old models that are obsolete.

Start small, think big. Don't worry about too many things at once. Take a handful of simple things to begin with, and then progress to more complex ones. Think about not just tomorrow, but the future. Put a ding in the universe.

People don't know what they want until you show it to them. That's why I never rely on marketing research. Our task is to read things that are not yet on the page.

Negative results are just what I want. They're just as valuable to me as positive results. I can never find the thing that does the job best until I find the ones that don't.

To invent, you need a good imagination and a pile of junk.
