I always see what’s... wrong. Would you want that? When I see a car or a rocket or spacecraft, I only see what’s wrong. I never see what’s right. It’s not a recipe for happiness.

I think there are too many smart people pursuing internet stuff, finance, and law. That is part of the reason why we haven't seen as much innovation.

When Henry Ford made cheap, reliable cars people said, 'Nah, what's wrong with a horse?' That was a huge bet he made, and it worked.

People often mistake technology for a static picture. It's less like a picture and more like a movie. It's the velocity of technology innovation that matters. It's the acceleration.

You could warm Mars up, over time, with greenhouse gases.

The biggest mistake, in general, I've made, is to put too much of a weighting on someone's talent and not enough on their personality. And I've made that mistake several times. I think it actually matters whether somebody has a good heart, it really does. I've made the mistake of thinking that it's sometimes just about the brain.

I think it's very important to have a feedback loop, where you're constantly thinking about what you've done and how you could be doing it better.
