"Endurance" and what it teaches us about drive

We have all been assigned the same book to read for this class, that being "Endurance" by Alfred Lansing, and while I initially thought that it would be a drag to have to read a seemingly unnecessary albeit entertaining story about a crew stranded in Antarctica for this class it very quickly grew on me and helped me to appreciate the almost bottomless well of willpower that we can pull from as people even in the most desperate of scenarios. I won't bore you with details but I believe the final 2 parts is where the book really shines in showing the will to persist as in order to try and save all his men, Shackleton had taken a small crew off of Elephant island to reach a whaling station almost 800 miles away from their current point and even after a 4 month journey all of the men left on the island were still alive when he returned for them which that in and of itself is a great feat of resilience. Not only was the burden of getting these men home safely placed onto the captains' shoulders, but the actual process of staying alive for the rest of the men in a harsh unforgiving environment for months upon months without actually knowing whether or not he would return is something that should be celebrated as well. Reading about these passages gave me the impressions that although we might not know it ourselves, we all have an inherent willpower that can allow us to overcome odds even as shown in "Endurance" and that especially is important to remember even in our modern age when faced with our own mundane albeit still just as important journeys into becoming more realized versions of ourselves which interestingly enough is exactly what the book I am reading up on "the willpower instinct" details in its entirety.
