The reason why every day is a joy to the normal child is that he fell heir at birth to a fortune of vitality and has not yet had time to squander all his substance in riotous or thoughtless living, or to overdraw his account in the Bank of Heaven on Earth. Every one of his days is a joy--that is, except in so far as his elders have impressed their tired standards of behavior too masterfully upon him. "Happy as a child"--the commonness of the phrase is in itself a commentary. In order to remain as happy as this for a century or so, all that a child has to do is to invest his vitality on sound business principles, and never overdraw or borrow. I shall not here go into the myriad details of just how to invest and administer one's vitality. For there is no dearth of wise books and physicians and "Masters of the Inn," competent to mark out sound business programs of work, exercise, recreation, and regimen for body, mind, and spirit; while all that you must contribute to the enterprise is the requisite comprehension, time, money, and will-power. You see, I am not a professor of vital commerce and investment; I am a stump-speaker, trying to induce the voters to elect a sound business administration. I believe that the blessings of climate give us of North America less excuse than most other people for failing to put such an administration into office. It is noteworthy that many of the Europeans who have recently written their impressions of the United States imagine that Colonel Roosevelt's brimming cup of vitality is shared by nearly the whole nation. If it only were! But the fact that these observers think so would seem to confirm our belief that our own cup brims over more plentifully than that of Europe. This is probably due to the exhilarating climate which makes America--physically, at least, though not yet economically and socially--the promised land. Of course I realize the absurdity of urging the great majority of human beings to keep within their vital incomes. To ask the overworked, under-fed, under-rested, under-played, shoddily dressed, overcrowded masses of humanity why they are not exuberant, is to ask again, with Marie Antoinette, why the people who are starving for bread do not eat cake. The fact is that to keep within one's income to-day, either financially or vitally, is an aristocratic luxury that is absolutely denied to the many. Most men--the rich as well as the poor--stumble through life three parts dead. The ruling class, if it had the will and the skill, might awaken itself to fullness of life. But only a comparatively few of the others could, because the world is conducted on a principle which makes it even less possible for them to store up a little hoard of vitality in their bodies against a rainy day than to store up an overplus of dollars in the savings bank.
