Watched it for the first time too.
What struck me most was just how Marc lived. He could have been anything, but the way he lived and his focus on what was important to him. Living in a stairwell, a tent, in a snow cave. Ignoring the pressures other put on him that didn't fit with the pure vision that he had, of what he was trying to obtain. All the while just just presenting a face of goofy kindness to anyone he interacted with.
Thats what I admire most about him, and wish that I could better implement into my own life....and also what I wish for my son or anyone. The level and type of climbing he was doing is something foreign to me that I can't begin to understand, and I'm sure I never will. But I can understand and admire the example that he lived outside of that.
