I'm glad someone mentioned this. It's an excellent narration of an excellent book.
I've been reading it to my son. It's got so many lessons on leadership, grit, foresight, courage etc. Very inspiring.
One thing that struck me was how sharp a judge of character Shackleton was. He picked the members of his crew after short or no interviews and was vindicated in his all his selections. That must have been a skill learned from time in the real world. Something which might be scorned on today for being biased or something else like that.
Dunno. His crew wasn't exactly "diverse" nor was it expecting to be.
He was manipulative in certain ways though I think all those moves were part of his leadership style. He also had personality quirks which jeopardised the situation on more than one occasion. Lansings book mentions an incident where her refused to gather meat when it was available because of some misguided idea of interpreting caution as a form of surrender or weakness that was anathema to his character and ego. He pulled through of course but there are moments when even a few of the the most loyal members of his crew started to have second thoughts about his leadership. I've been reading the book to my young son. He thinks of Shackleton as a hero but was "angry" at him when I read the part about dropping the meat.
