But there are many kinds of travel, many reasons to move. Sometimes you travel so that the process of becoming that is your inner life has an external correlative in your movement across space. You may not know how to save your soul, but you know how to put one foot in front of another. You may not know the way to stop being so furious you can hardly sleep, but you can buy a road map of the American West. And then you can put the need on like a knapsack and wear it along your journey, wear it out, shed it, find that it belongs to someone you no longer are. This is pilgrimage, which is not as pretty as it sounds. It’s not running away, though: it’s running toward.
Rebecca Solnit, "The Art of Arrival"
