When I was 23, I set off round the world. Just like the quote, I quit my job, bought a ticket, got a tan, fell in love and never really returned. Before I left, I read an article by someone recently home after a long trip. She said, "The feeling you get when the airplane leaves the tarmac is one you'll never stop chasing." At the time I was 23, arrogant and thought I knew better, so I didn't pay much attention. Five years later and she was right, I've never quite shaken the wanderlust.
