To this end the schools are doing much. Settlement workers are contributing their part. Welfare work is becoming popular in certain places. Local clubs are being organized to develop interest in local improvement, literature, politics, ethics, religion, music, athletics. These agencies are so beneficial in results that they are being generously encouraged by business men.
Upon entering business every young man should select some form of endeavor or activity apart from business to which he shall devote a part of his attention. This interest should be so <p 221> absorbing that when he is thus engaged, business is banished from mind.
This interest may be a home and a family; it may be some form of athletics; it may be club life; it may be art, literature, philanthropy, or religion. It must be something which appeals to the individual and is adapted to his capabilities. Some men find it advisable to have more than a single interest for the hours of recreation. Some form of athletics or of agriculture is often combined with an interest in art, literature, religion, or other intellectual form of recreation. Thus Gladstone is depicted as a woodchopper and as an author of Greek works. Carnegie is described as an enthusiast in golf and in philanthropy. Rockefeller is believed to be interested in golf and philanthropy, but his philanthropy takes the form of education through endowed schools. Carnegie's philanthropy is in building libraries. If the lives of the great business men are studied it will be found that there is a great diversity in the type of recreation chosen; but philanthropy, religion, and athletics are <p 222> very prominent—perhaps the most popular of the outside interests.
These interests cannot be suddenly acquired. Many a man who has reached the years of maturity has found to his sorrow that he is without interests in the world except his specialty or business. With each succeeding year he finds new interests more difficult to acquire. Hence young men should in their youth choose wisely some interests to which they may devote themselves with perfect abandon at more or less regular intervals throughout life.
The more noble and the more worthy the interest, the better will be the results when considered from any point of view. Indeed, the interests which we call the highest are properly so designated, because in the history of mankind they have proved themselves to be the most beneficial to all.
CHAPTER X
THE RATE OF IMPROVEMENT IN EFFICIENCY
NO novice develops suddenly into an expert. Nevertheless the progress made by beginners is often astounding. The executive with experience is not deceived by the showing made by new men. He has learned to accept rapid initial progress, but he does not assume that this initial rate of increase will be sustained.
The rate at which skill is acquired has been the subject of many careful studies. The results have been charted and reduced to curves, variously spoken of as ``efficiency curves,'' ``practice curves,'' ``learning curves,'' according to the nature of the task or test. Some of these dealt with the routine work of office and factory. In others typical muscular and mental activities were observed in a simpler form than could be found in actual practice. <p 223> <p 224>
Five of my advanced students joined me in strenuous practice in adding columns of figures for a few minutes daily for a month. Our task was to add 765 one-place figures daily in the shortest possible time. No emphasis was placed on accuracy, but each one tried to make
