Traveling means having to present a coherent version of yourself each day, to every person you meet. It is a still pond off of which your image reflects right back to you, and allows the chance for constant introspection and reinvention.
You ask yourself “who am I” and you get the chance to calibrate your answer. At a distance from the bonds, promises, and images of yourself that solidify you, you learn as much about your own identity as you do about those things outside you.
We are all, after all, the sum of the ideas that we have of ourselves and the world around us.
