When you go to the mountains, you see them and you admire them. In a sense, they give you a challenge, and you try to express that challenge by climbing them.
I think I mainly climb mountains because I get a great deal of enjoyment out of it. I never attempt to analyze these things too thoroughly, but I think that all mountaineers do get a great deal of satisfaction out of overcoming some challenge which they think is very difficult for them, or which perhaps may be a little dangerous.
I think the really good mountaineer is the man with the technical ability of the professional and with the enthusiasm and freshness of approach of the amateur.
I'm sure the feeling of fear, as long as you can take advantage of it and not be rendered useless by it, can make you extend yourself beyond what you would regard as your capacity. If you're afraid, the blood seems to flow freely through the veins, and you really do feel a sense of stimulation.
It is not the mountain we conquer but ourselves.
