Postmodern Tourism : An Interview with Pico Iyer:

I think that what she must have found, and most of us do too, is that home is essentially a set of values you carry around with you and, like a turtle or a snail or whatever, home has to be something that is part of you and can be equally a part of you wherever you are. I think that not having a home is a good inducement to creating a metaphysical home and to being able to see it in more invisible ways.
