Query: Essential Mountaineering Literature

I've read a lot of mountaineering/climbing literature and this is by far one of the best books I ever had the pleasure of reading. Often, such books focus too much on the climbs themselves with unnecessary details and technicalities. This book is different in that the emotions, risks, and philosophies of climbing are the focus and to hear it from one of the greats of all time, it makes it even more meaningful. Great commentary on his difficulties weighing family life against his goals and his thoughts on how to deal with the many losses he sustained throughout his journey. A must read for any adventurist/aspiring/accomplished mountaineer.
