What does Krakauer see as his strengths in climbing everest? What are his weaknesses?

From the text:

I'd logged considerably more time on technical rock and ice than most of the other clients and many of the guides. But technical expertise counted for next to nothing on Everest, and I'd spent less time at high altitude than virtually every other climber present. Indeed, here at Base Camp-the mere toe of Everest-I was already higher than I'd ever been in my life.

You're very welcome.
