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.
We will stomp to the top with the wind in our teeth.
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.
