" By and by your attention becomes so intensely focused that you no longer notice the raw knuckles, the cramping thighs, the strain of maintaining nonstop concentration. A trancelike state settles over your efforts; the climb becomes a clear-eyed dream. Hours slide by like minutes. The accumulated clutter of day-today existence—the lapses of conscience, the unpaid bills, the bungled opportunities, the dust under the couch, the inescapable prison of your genes—all of it is temporarily forgotten, crowded from your thoughts by an overpowering clarity of purpose and by the seriousness of the task at hand. At such moments something resembling happiness actually stirs in your chest, but it isn’t the sort of emotion you want to lean on very hard. In solo climbing the whole enterprise is held together with little more than chutzpah, not the most reliable adhesive. "
