"I travel because I like to move from place to place, I enjoy the sense of freedom it gives me, it pleases me to be rid of ties, responsibilities, duties, I like the unknown; I meet odd people who amuse me for a moment and sometimes suggest a theme for a composition; I am often tired of myself and I have a notion that by travel I can add to my personality and so change myself a little. I do not bring back from the journey quite the same self that I took"
