“I changed as a result of that bus trip, in a fundamental way. It was the sort of change that’s important not because it alters your concrete circumstances in some way (wealth, security, fame) but because it hints at what might be possible and therefore spurs you on, beyond the immediate exhilaration, beyond any subsequent disappointments, to retrieve that thing that you once, ever so briefly, held in your hand. That bus ride kept me going, I think. Maybe it still does.”
