The story of Shackleton’s leadership on the Endurance expedition is extraordinary. It is recommended reading for every adolescent (I’m sorry I only heard of it as an adult) and anyone who wants to learn about real leadership. Incredible but true story. Start with Alfred Lansing’s book
then read Shackleton’s own account, South.
Read both, Shackleton was a bad@ss.
One more amazing thing was that so many of those guys who survived this ordeal went on to WW1 and were killed in combat.
