The greatest danger in life is not to take the adventure.
Because it is there [famous explanation for wanting to climb Mount Everest].
Because it's there. (when asked why he wanted to climb Everest)
To struggle and to understand. Never the last without the first. That is the law.
What we get from this adventure is just sheer joy. And joy is, after all, the end of life. We do not live to eat and make money.
The first question which you will ask and which I must try to answer is this; What is the use of climbing Mount Everest? and my answer must at once be, it is no use. There is not the slightest prospect of any gain whatsoever.
