I don't have an issue with what you do in the church, but I'm going to be up in your face if you're going to knock on my science classroom and tell me they've got to teach what you're teaching in your Sunday school. Because that's when we're going to fight.

When I wrestled, I would set aside the time to wrestle, so that in my mind it didn't interfere with my study time. If I'd say, "I'm going to study this many hours, then I'm going to go work out and wrestle," then when that time comes, you don't feel like you should be doing something else. That helped me psychologically. But otherwise? When I'm wrestling, I'm not studying the universe. And when I'm studying the universe, I'm not wrestling.

Extreme skepticism and extreme gullibility are two equal ways of not having to think at all. And I don't think I'm the first to say that.

So when I think of, what is the meaning of life, to me, that's not an eternal unanswerable question. To me it is in arms reach of me every day.

If the purpose of the universe was to create humans then the cosmos was embarrassingly inefficient about it.

When you advance a frontier and you do tomorrow what's never been done today, you have to innovate to make that happen. You become an innovation culture. When I grew up, every time I turned around it was, "Oh, here's the longest bridge or the deepest tunnel or the fastest airplane." And I originally thought that was just kind of like a pissing contest with men with too much testosterone. And then I realized that to make the tallest building you have to innovate. To make the fastest train you have to design the train in a way that it's never been designed before.

You don't want to raise a kid in a culture where the kid who asks the most questions is annoying. You want a culture where the kid who asks the most questions gets awards and gets another piece of cake.
