"The higher I climbed, the more comfortable I became.... The accrued guilt and clutter of day-to-day existence — the lapses of conscience, the unpaid bills, the bungled opportunities, the dust under the couch, the festering familial sores, 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."
