Travel is not really about leaving our homes, but leaving our habits.

Mr. Trump doesn't radiate many of the qualities I respect. But what do I know? I've never met Trump. I know he's savvy enough to change his tune according to his audience and I don't know very much at all about how government works.

Travel, in the superficial sense at least, is a good cure for loneliness. When you travel, especially in the third world, you quickly find that you get more friends than you know what to do with.

Literally, when you wake up at 9 o'clock in the morning in Havana you don't know where you'll be at noon. But it's a safe guess that you'll either be married, arrested, or in the midst of some incredible transaction where somebody is stealing your passport or paying you in Dominican pesos for it, or whatever. It's a wild place.

I would say that by virtue of transforming politics, [Dalai Lama] is in fact easily underestimated.

If you'd asked me some years ago, I would have said [Dalai Lama] is an extraordinarily compassionate, clear-sighted, calm human being. But now, I'm more convinced than ever that his political positions as well as his spiritual positions arise out of such precise and realistic thinking that they're extremely sound.

I take very seriously the sense of our living these days in a global neighborhood. And the first sensible thing to do in such circumstances, as well as one of the most rewarding things, is to go and meet the neighbors, find out who they are, and what they think and feel. So travel for me is an act of discovery and of responsibility as well a grand adventure and a constant liberation.
