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

I do not want to waste any time. And if you are not working on important things, you are wasting time.

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

Education, actual learning - it is hard work. It's very personal. Your parents don't teach you anything. Your teachers don't teach you anything. The government doesn't teach you anything. You read it. You don't understand it; you read it again. You break a pencil and read it again.

My biggest failure is I have too many to talk about.

Americans thinking that America will continue to lead the world in innovation and quality of life without some quick and serious educational improvements are dangerously delusional.

I don't work on a project unless I believe that it will dramatically improve life for a bunch of people.
