Flying has always been to me this wonderful metaphor. In order to fly you have to trust what you can't see. Up on the mountain ridges where very few people have been I have thought back to what every flyer knows. That there is this special world in which we dwell that's not marked by boundaries, it's not a map. We're not hedged about with walls and desks. So often in an office the very worst thing that can happen is you could drop your pencil. Out there's a reminder that are a lot worse things, and a lot greater rewards.
