Those who are anxious to do good in the spreading of health knowledge among their friends can serve best by getting health themselves. If a physical wreck evolves into good health there will be considerable comment and inquiry. This is the opportunity to tell what nature will do and inform others where to obtain a good interpretation of nature's workings. A little practicing is worth more than a great deal of preaching. The truth is the truth, no matter what the source, but it is more effective if it comes from one who lives it. I have gone into the subject of health cranks so deeply because there are so many of them. They get a little knowledge and then they believe they are masters of the subject. The right attitude toward proper living, and especially toward proper eating is: "I shall try to conduct myself so as to be healthy and efficient. If others desire my help, I shall try to indicate the way to them. Right living is no sign of superior goodness or merit, being a matter of higher selfishness, so I deserve no credit for it. Although health is very important, I shall refrain from attempting to force my will on others." After conquering ourselves it is time to begin making foreign conquests, but by that time the realization comes that in the end it is best to leave others free to work out their own salvation. The desire is strong to mould others according to our pattern, but those who size themselves up honestly soon come to the conclusion that they are so imperfect that perchance some other pattern is fully as good. _Postponing happiness_: One peculiar state of mind is to refuse to be happy at present. The romantic girl and boy think they can not be happy until they are married. After marriage they find that they have to gain a certain amount of wealth before happiness comes. Then they have to postpone it for social position. They continue postponing happiness from time to time and the result is that they never attain it. Happiness is not a great entity that bursts upon us, transforming us into radiant beings. It is a comfortable feeling that brings peace and places us in harmony with our surroundings. It can best be gained by doing well each day the work that is to be done, cheerfully giving in return for what is received. Happiness is largely a habit. It is as easy to be bright and cheerful as it is to be sad and doleful, and much more comfortable. If we look for the best we will find beauty even in the most unpromising places. If we are looking for tears and woe, we can easily find them. We can get along without happiness, but it adds so much color and beauty to life, it makes us so much better, it helps us so much to be useful that it is folly to do without it. It is not gained by narrow selfishness. Those who forget themselves most and are kind and considerate find it. By giving it to others we get it for ourselves. Ecstasy and rapture are emotions of short duration. They are so exhilarating that they soon wear out.
