My biggest worry is I'm running out of time and energy. Thirty years ago I thought 10 years was a really long time.

We cant live any more in a world which is based on stuff and not ideas. If you want to live with the world of stuff, were all doomed.

In a free society, you get what you celebrate.

More than ever, the world needs good engineers. However, the pool of talent is shrinking not growing.

If you're going to fail, you might as well fail at the big ones.

In the culture of America, in a free culture, you get what you celebrate. And in this culture, we have two obsessions, become a group that becomes a group that celebrates sports heroes and entertainment heroes. There's no room left for kids to see even a little bit of the opportunities to really, really get excited about becoming an inventor, an engineer, or a scientist, a problem solver.

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