What draws me in is that a trip is a leap in the dark. It's like a metaphor for life. You set off from home, and in the classic travel book, you go to an unknown place. You discover a different world, and you discover yourself.

"Reading alters the appearance of a book. Once it has been read, it never looks the same again, and people leave their individual imprint on a book they have read. Once of the pleasures of reading is seeing this alteration on the pages, and the way, by reading it, you have made the book yours."

Paul Theroux
