Sir Ernest Shackleton was an explorer. He led several expeditions to the frozen antarctic. On one such expedition, on the ship Endurance, he and his crew became stranded in the ice. They had to abandon ship and drag their lifeboats over the frozen flows to open water. From their, they had to sail over treacherous waters to reach civilization. It is a harrowing story. (You can read more in Caroline Alexander’s The Endurance: Shackleton’s Legendary Antarctic Expedition.)

Alexander points out that part of Shackleton’s genius was as a leader. That was demonstrated in how he selected his men. “The general peace that prevailed on the Endurance had not come about by accident and owed something to the manner in which Shackleton had selected the men in the first place. When James [one of the science officers] presented himself for his interview, the great explorer had bewildered him by asking not about his suitability for a major polar expedition, or details of his scientific work—but whether he could sing.”
‘Oh I don’t mean any Caruso stuff,’ Shackleton had continued, ‘but I suppose you can shout a bit with the boys?’ The question proved to be uncannily appropriate. What he was looking for was an ‘attitude,’ not paper qualifications.”
