I think that America is an ideal place for the privileged homeless, who are used to different cultures. It's easiest and most accommodating because it is a country of exiles and immigrants and newcomers. There are no walls, in that sense. There is always the sense that traditions are being made as we speak. So you can slot yourself in. If you are living at a distance in society, this is one of the most congenial societies to live in.

So travel for me is an act of discovery and of responsibility as well a grand adventure and a constant liberation.

I think America the symbol and America the notion are still very different from America the nation. What's touching and almost regenerative is that whatever is happening in the reality of America, where there is a murder rate worse than Lebanon's and where there is so much homelessness and poverty, still America will be a shorthand throughout the world for everything that is young and modern and free.

To step away from the world isn't to draw back; it's actually a way to tune in.

The Australians, it seems to me, thrive on their remoteness from the world and see it as a way of keeping up a code of "No worries, mate," while peddling their oddities to visitors: nonconformity is at once a fact of life for many, and a selling point.

We travel, in essence, to become young fools again - to slow time down and get taken in, and fall in love once more.

As soon as I began to talk to Dalai Lama, I realized that Chinese and Tibetans from his point of view are mostly the same. And as he pointed out during the recent disturbances, the Chinese are suffering under a tough government much as the Tibetans are.
