I have long known that it is part of God's plan for me to spend a little time with each of the most stupid people on earth.

There are three stages in scientific discovery. First, people deny that it is true, then they deny that it is important; finally they credit the wrong person.

When you consider it from a human perspective, and clearly it would be difficult for us to do otherwise, life is an odd thing. It couldn't wait to get going, but then, having gotten going, it seemed in very little hurry to move on.

Still, I never really mind bad service in a restaurant. It makes me feel better about not leaving a tip.

If you drive to, say, Shenandoah National Park, or the Great Smoky Mountains, you'll get some appreciation for the scale and beauty of the outdoors. When you walk into it, then you see it in a completely different way. You discover it in a much slower, more majestic sort of way.

I still enjoy traveling a lot. I mean, it amazes me that I still get excited in hotel rooms just to see what kind of shampoo they've left me.

Traveling is more fun - hell, life is more fun - if you can treat it as a series of impulses.
