But there are men for whom the unattainable has a special attraction. Usually they are not experts: their ambitions and fantasies are strong enough to brush aside the doubts which more cautious men might have. Determination and faith are their strongest weapons. At best such men are regarded as eccentric; at worst mad…Everest has attracted its share of men like these. Their mountaineering experience varied from none at all to very slight – certainly none of them had the kind of experience which would make an ascent of Everest a reasonable goal. Three things they all had in common: faith in themselves, great determination, and endurance.
