I'm derrick sivers, and this is travel without social praise. I suggested a couple should only do it if they don't bring a camera. Why? Because we often live for others without even realizing it. We like the social reward of saying we're travelling the world. If doing something makes us that kind person, is it still true if we don't announce it? Go to sivers dot org.
I met a couple who were thinking of quitting their jobs and travelling the world for a year.
