Writers and travellers alike do their best work when they don’t know what they’re looking for; disorientation requires problem-solving, and a new landscape holds secrets still. These days, I never totally unpack my suitcase. I buy only folding toothbrushes. I leave, often, on short notice—my record is three and a half hours before takeoff, for a transatlantic trip—and I like my mind best when it’s on the move. To land somewhere unfamiliar is to force yourself into alertness, to redraw whatever maps you have, to set the stage for creativity more than mere pattern-matching productivity.
