A few years ago my house burned down, and I lost everything I owned; all my notes, all the books I hadn't yet completed, all my photos and hopes and letters. And yet traveling helped me see this as a liberation: to live more at home as if I were on the road, to savor the freedom from a past and from possessions, and to think back on all the people I had met, in Tibet and Morocco and Bolivia, who would still have thought of my life as luxurious. Most of the people one meets while traveling deal with more traumas every day than the privileged among us meet in a lifetime. That's how traveling humbles and inspires.
