Above all, cultivate the habit of happiness. Whatever else you may neglect, do not neglect that, for the happy habit is the greatest treasure that any individual can possess. Happiness depends largely upon physical conditions. With poor health, perfect happiness rarely exists; therefore it is your duty to be healthy, and the possession of health is in the majority of cases a matter of personal endeavor. But although the physical is important in health, yet the physical is dominated by the mental, and if you resolve to be happy, you can succeed. Commence this day, by saying to yourself, I am happy; I will be happy. Start out with the resolve that you will at least do some one thing to-day that will bring happiness to another, in the form of some simple service. Even if no such opportunity presents itself (although opportunities are never lacking), you can at least bestow cordial and cheerful greetings on those with whom you come in contact. No surer road to personal happiness can be found than endeavoring to make others happy. If you find it difficult to be cheerful, there is more need to look to your surroundings. Read none but cheerful books; cultivate cheerful acquaintances. You will be amply repaid for your endeavors to cultivate the habit of happiness. From the standpoint of health, it is a profitable proceeding, for joy quickens the circulation. You can get the happiness habit if you wish to, and it is your duty to yourself and those around you to do so. If the clouds are lowering, do not give way to depression. Rouse yourself. Look for the rift in the clouds, disclosing the little patch of blue, and hope for the triumph of fair weather over foul. Even if you do not attain the degree of happiness you anticipated, you will find yourself improved, mentally, morally and physically. Get the habit, remembering that "a happy and contented mind is a continual feast." And now, in conclusion, I would ask the reader to carefully consider the facts herein set forth relating to disease and its treatment, to weigh the testimony AGAINST the old system, and FOR the new, and let sober reason decide which of the two is the more rational. Bring the same dispassionate judgment to bear on this question that you would on a matter involving your financial welfare. It will amply repay you to do so, for the matter at stake is a weighty one. The preservation of health is a DUTY that each member of the human family owes to self and friends.
