“One sad thing about this world is that the acts that take the most out of you are usually the ones that people will never know about.

(from 'Celestial Navigation')”

“The things most people want to know about are usually none of their business.”

“There are the people in this world who act, and the people who scheme. The ones who act get things done, and the ones who scheme try to take credit for it. You must know that as well as I do.”

“Because that's the thing about mean people: They make you think that the world will never work, that there are divides that you will fall into if you approach. It takes a whole lot of good people to fill in the breach created by a single mean one.”

“I was constantly surprised by how much people didn’t know. That’s one of the things about traveling, one of the things you learn: many people in the world, even educated ones, don’t know much, and it doesn’t actually matter at all.”

“It's a funny thing about weaknesses…. Most people will tell you they know their weaknesses. When asked, they'll tell you, 'Well for one thing, I'm overgenerous.”

“People have curious attitudes about nudity just as they have about sex. Nudity and sex are the most commonplace things in the world. Yet people often act as if they were things that only existed on Mars.”

But I will admit that it is also the most incomprehensible number in the world. Beyond this particular dimension I know only one thing which is supernatural, even though it may well be the reality that affects mortal men most deeply; and that is Time. And when one comes to think about this strange place I was telling you about, the world that is only One, and its connection with the only supernatural thing we know, Time, then everything ceases to be higher or lower than anything else, larger or smaller.”
