Related to this in minor key is the doubtful condition of mind where the individual has to do things several times before he is sure they are properly done. For instance, there is the man who must try the office door several times to be sure that it is locked and after being satisfied on this point he is obliged to unlock it and investigate the condition of the safe door. Then it is necessary to attend to the office door two or three times again. This kind of doubtfulness takes many forms. It does no special harm except that it leads to much waste of time. Such people should teach themselves concentration, thinking about one thing only at a time, until they learn that when a thing is done it is properly done.
Judging: Many insist on passing judgment on everything and everybody that come to their notice. Every individual has to be placed with the sheep or the goats. This is a great waste of time. Each one of us can know so little about the majority of individuals we meet and of the vast volume of knowledge that is to be had that if we try to judge everyone and everything, our opinions become worthless. Wise people are never afraid to say, "I don't know." If it is necessary to judge, let there be kindness.
Volunteering advice: This is another annoying habit. It is very well to give advice if it is desired and asked for, otherwise it is a waste of time. Take a person with a cold, for example: If he meets twenty people he may be told of fifteen different cures for it, ranging from goose grease on a red rag to suggestive therapeutics. If he were to act upon all the advice received there would probably be a funeral. It is best to be sparing with advice. Those who have any that is worth while will be asked for it and paid for their trouble. Free advice is generally worth what it costs.
Cranks: Many allow themselves to get into a mental rut with their thoughts running almost entirely to one subject. This is a mild form of insanity, for normal people have many interests. These people are the cranks. They can talk volumes about their favorite topic, often of no importance. It may be some peculiar religion or ethics; or that Bacon wrote the plays of Shakespeare; or some health fad, or almost any subject.
Of all the cranks the diet crank is one of the most annoying, for he has three good opportunities to air his views each day. With the best meaning in the world he does more harm to the cause of food reform than do the advocates of living in the good old way, eating, drinking and being merry and dying young. When people become possessed of too much zeal and enthusiasm regarding a subject, they are sure that their knowledge is the truth and they insist upon trying to enforce their way upon others, resent having their old habits interfered with forcibly. Those who are too persistent and insistent produce antagonism and prejudice in the minds of others, and then it is almost impossible to impart the truth to them, for they will neither see nor hear.
To be able to influence others for better is a grand and glorious thing, but it is well to remember that we can not force knowledge which is contrary to popular thought upon others suddenly. Those who change a well rooted opinion generally do so gradually. When they first hear the truth, they say it is ridiculous. After a while they think there may be something in it. At last they see its superiority over their former opinions and accept it. It requires infinite patience on the part of the educators to impart unpopular knowledge to other adults, no matter how much truth it contains.
The truth about physical well-being is so simple and so self-evident that it is exceptionally hard to get an unprejudiced audience. From the time when the ancient heathen priests were the healers until today the impression has been that health and healing are beyond the understanding of the common mind, and therefore people are willing to be mystified. The mysterious has such a strong appeal in this world of uncertainties that it is more attractive than the simple truth. Mystery simply demands faith. The truth compels thinking and thoughts are often painful.
By all means, avoid being overinsistent in trying to impart health knowledge to others. All who have a little knowledge of the fundamentals of health and growth know that useful men and women are going into degeneration and premature death constantly, because of violated health laws. If these people on the brink, who can yet be saved by natural means, are told how it can be done, they generally either refuse to believe it, or they have led such self-indulgent lives that it is beyond their power to change. The knowledge often comes too late.
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.
