These rambling thoughts will serve to show the reader whether it is worth while to go any further. The following chapters are devoted to an exposition of a workable knowledge of how to retain health, and how to regain lost health in ordinary cases. They will teach how to get dependable health, how to remain well in spite of climatic conditions, bacteria and other factors that are given as causes of disease, and how to more than double the ordinary span of life. Good health and long life result in better work, increased earning capacity and efficiency of body and mind, greater understanding, and more enjoyment of life. It gives time to cultivate wisdom. CHAPTER II. MENTAL ATTITUDE. On mental questions there is a wide divergence of opinion. At one extreme some say that all is mind, at the other, that life is entirely physical, that the mind is but a refined part of the body. Most of us recognize both body and mind, and realize that life has a physical basis. If some are pleased to be known as mental phenomena, no harm is done. All desire to make a success of life. What would be a success for one would be a failure for another. It all depends on the point of view. Broadly speaking, all are successful who are helpful, whether it be in furnishing pleasure or necessities to others. The humble may be as successful as the great, yes even more so. Wealth and success are not synonymous, as many think. Among the failures must be counted many of the wealthy. Financial success is not real success unless it has been gained in return for valuable service. The men of initiative deserve greater rewards than the plodders and these rewards are cheerfully given. A little genuine love and affection can bring more beauty and happiness into life than wealth, and neither can be bought with money. The best and most satisfying form of success comes to him who helps himself by helping others. "It is more blessed to give than to receive," has passed into common currency; but the more we give the more we receive. He who loves attracts love. He who hates is repaid in kind. "He who lives by the sword shall perish by the sword." The enjoyment of the fruits of one's labor is a part of success. Some make a fetish of success and thus lose out. Others are so ambitious that in their striving they forget to live. A little ambition is good; too much sows the seed of struggle, strife and discontent and defeats its own ends. Those who do evil because the end justifies the means have already buried some of the best that is in them.
