Ed Viesturs is well known in the climbing community, holding a number of summit records and having written a number of books (all of which I recommend, they are great reading). In light of the above, The Atlantic Monthly decided to do a short piece on Ed and his bottled-oxygen-less climb of Everest in 1990. You can read the article HERE.
The one takeaway that strikes me most from his writings and speeches is this one quote: “Getting to the top is optional, getting down is mandatory.”
This is pretty self-explanatory.
