Men simply cannot resist exercising and stretching to their fullest tether the faculties and aptitudes with which they each happen to be specially endowed. One born with an aptitude for painting is dull and morose and fidgety until he can get colours and a brush into his hand and commence painting. Another is itching to make things--to use his hands and fashion wood or stone or metal into forms which he is continually creating in his mind. Another is restless until he can sing. Another is ever pining to be on a public platform swaying the audience with his oratory and playing on their feelings as on a musical instrument. Each has his own inner aptitude which he aches to give vent to and bring into play. And more than this, he secretly owns within himself an exceedingly high standard--the highest standard--of what he wants to attain to along his own particular line, and he is never really content in his mind and at peace with himself when he is not stretching himself out to the full towards this high pinnacle which he has set before him. Now fortunately all men are not born with the same aptitudes. We do not all want to sing or all want to orate or all want to paint. Some few want to climb mountains. These men love to pit themselves against what most others would consider an insuperable obstacle. They enjoy measuring themselves against it and being forced to exercise all their energies and faculties to overcome it. The Duke of the Abruzzi is as good an example of this type as I know. He was never happy until he had discovered some inaccessible and impracticable mountain and then thrown himself against it and come to grips with it in dead earnest and either conquered it or been thrown back from it utterly and completely exhausted, but with the satisfaction that anyhow he had exercised every nerve and muscle and faculty to the full. His native mountains he had early conquered over and over again, so he had to look further afield to Mount Elias in Alaska and Ruwenzori in East Africa; and having vanquished these he would doubtless have turned his eyes to Mount Everest if for political reasons the way to that mountain had not been barred, and he was compelled therefore to look to the next highest mountain, namely, the peak K2 in the Karakoram Himalaya in the neighbourhood of which he attained to a greater height, 24,600 feet, than has yet been attained by any man on foot.
