I don't want to think about how many people have thought or still think that I'm crazy.

Nothing that has value, real value, has no cost. Not freedom, not food, not shelter, not healthcare.

There is just so much stuff in the world that, to me, is devoid of any real substance, value, and content that I just try to make sure that I am working on things that matter.

I'd rather lose my own money than someone else's.

What really makes it an invention is that someone decides not to change the solution to a known problem, but to change the question.

I think an education is not only important, it is the most important thing you can do with your life.

Most of the time you will fail, but you will also occasionally succeed. Those occasional successes make all the hard work and sacrifice worthwhile.
