I am just back from a life-changing safari in southern Africa. Coincidental to the trip, I have been reading Paul Theroux's "Deep South." I have read many of his books, and in the last pages of "Deep South" he writes:
"Travel has always been a way of defeating this sinking feeling, partly because travel is a form of escape, and travel itself--the elemental farewell--becomes the fugitive fantasy of a new life, travel inspiring a sense of hope. I began my real life, my life of intensity and solitude and discovery, as a twenty-two year-old traveler in Africa, then elsewhere, everywhere, and that formed me as a writer, alert to every sound and smell and to the pulses of the air."
