On Travel - Jean-Paul Sartre

It must be such an upheaval. If I were ever to go on a trip, I think I should make written notes of the slightest traits of my character before leaving, so that when i returned I would be able to compare what I was and what I had become. I’ve read that there are travellers who have changed physically and morally to such an extent that even their closest relatives did not recognize them when they came back.
