supply the needed stimulus and stir him to sudden display of all his strength.
I recently conducted a series of experiments on college athletes to determine whether coaching could actually increase a man's strength when he was already trying his ``best,'' and whether he could continue to work after he was ``completely exhausted.'' I put each man at work on machines which allowed him to exert himself to his utmost and measured his accomplishment. While he was thus employed, the coach began urging him to increase his exertion. Ordinarily the increase was marked--sometimes as much as fifty per cent.
Again, when the man had exhausted himself without coaching, the extra demand would be made on him; usually he was able to continue, even though without the coaching he had been unable to do any more. There was, of course, a point of exhaustion at which the coaching ceased to be effective.
_The tests proved conclusively that when a man is doing what he believes to be his best, he is still_
_able to do better; when he is completely exhausted, he is, under proper stimulus, able to continue_.
Before a horse is started in a race it is vigorously exercised, ``warmed up.'' To the uninitiated this process seems so strenuous as to defeat its purpose by wearing out the strength of the horse. Every horseman knows, however, that the animal cannot attain top speed till after it has undergone this severe discipline.
In training for a contest an athlete usually takes long runs. Soon after the start he feels weary and exhausted, but, by disregarding this feeling and continuing to run, a sudden change comes over him commonly known as ``getting his second wind.''
Thus the runner feels wave upon wave of exhaustion followed by waves of invigoration. Had he stopped when he first began to tire, he never would have known of his wonderful reserve fund of strength which can be drawn upon only by passing through the feeling of exhaustion. He seems to be able to tap deeper and deeper reservoirs of strength.
_Many men have never discovered their reserve stores of strength because they have formed the fixed habit of quitting at the first access of weariness_.
Thus they never become conscious of the wonderful resources which might be used if they were willing to disregard the trifling wave of weariness.
Our best energies are not on the surface and are not available without great exertion. We have to warm up and get our second wind before we are capable of our best physical or mental accomplishments. All our muscular and psychical processes are dependent upon the activity of the nervous system. This activity seems to be at its best only after repeated and vigorous stimulation and after it has reached down to profound and widely distributed centers.
_Most of us never know of our possible achievements because we have never warmed up and got our second wind in our business or professional affairs_.
When an individual succeeds in tapping his
reserve energies, others marvel at the tremendous tasks he accomplishes. They judge in terms of superficial energy, and for such the results would, of course, be impossible, even though many of the admiring spectators could actually equal or excel the deed.
Consider for a moment the work achieved by Mr. Edward Payson Weston who recently walked the entire distance from New York to San Francisco without halt or rest in one hundred and four days. Throughout the entire journey Mr. Weston covered about fifty miles daily, once attaining the remarkable distance of eighty-seven miles in twenty-four hours. Though Mr. Weston is seventy years of age, at the close of the walk he seemed to be relatively free from exhaustion and undaunted in spirit.
The work accomplished by such men as Gladstone and Roosevelt is incomprehensible to most of us who have never undertaken more than puny tasks. These men retain their strength and in no way seem to be undermining their health by the accomplishment of their
Herculean labors. Body and mind seem to respond to the demands made upon them. Their periods of sleep and their vacations seem to be no more than the hours and days of rest required by those of us who accomplish infinitely less.
No need, however, to go beyond
