Just this week I read a story about Henry Worsley who died trying the same thing: https://www.newyorker.com/magazine/2018/02/12/the-white-dark... . After reading, I wonder if you have to a certain level of insanity for doing something like this.
I have to wonder though, how long does it take for the afterglow of such a massive accomplishment to wear off and to start asking yourself "what now?"
