I would like to fly in space. Absolutely. That would be cool. I used to just do personally risky things, but now I've got kids and responsibilities, so I can't be my own test pilot. That wouldn't be a good idea. But I definitely want to fly as soon as it's a sensible thing to do.

You want to have a future where you’re expecting things to be better, not one where you’re expecting things to be worse.

And we need things in life that are exciting and inspiring. It can't just be about solving some awful problem. There have to be reasons to get up in the morning.

If anyone thinks they'd rather be in a different part of history, they're probably not a very good student of history. Life sucked in the old days.

I read books and talked to people. I mean that's kind of how one learns anything. There's lots of great books out there & lots of smart people.
