Susan Ershler, Author, Conquering the Seven Summits of Sales: From Everest to Every Business

In 2002, while relaxing at Everest Base Camp, I fell into conversation with Dan, a fellow climber about to make his fifth attempt to reach the summit alone. Dan was determined to be completely self-sufficient, carrying all of his own gear and climbing without a guide. I wondered why anyone would take on such a huge challenge without accepting even a modicum of help. But I wished him luck and rejoined my team to prepare for our climb of the treacherous Khumbu Ice Fall, the first major obstacle on our route to the summit.
