It seems that not anything worth while in this world is gained without self-fighting and worry. The great things that are accomplished by men and women are accomplished only through will power, determination and concentration. Determination is different from will power in this respect: one may be determined to do a thing but find that she has not the nervous power to carry out the determination. In other words, the nervous force is really the basis of all will power. So all the factors which go to make for self-control and concentration upon whatever you have decided upon doing, are dependent upon a good and perfectly adjusted nervous system. Without a powerful nervous force we would be nothing but eating and sleeping animals. The men and women who do not know from any personal feeling that there is a tremendous force in a trained nervous system are those who do nothing for the world’s progress; they only eat, sleep and automatically labor. Many who have plenty of nervous force but do not know what it means, and hence cannot control it and use it for the benefit of man and themselves, are those who throw it away in dissipations, abnormal excitement and riotous living. To have a highly-sensitive nervous organization is the greatest gift a woman can have; but unless she early knows its value and how to train it, it becomes a curse to her. It will run away with all her impulses――good and bad――and finally separate her from her womanly stability. We hear a lot about “nervous women and girls;” and that the condition is increasing, due to our rapid way of living and all the pressure of trying to keep up the pace civilization has set. I have lived most of my life among nervous women and girls, and have come to the conclusion that the truth of the matter is, that instead of being due to our rapid pace of living and working, it is really due to the fact that most girls have never been taught to train and control their nervous forces. These nervous girls and women are mostly those who are not over-nervous, but simply never have developed a nervous force that could keep pace with their physical and emotional activities. It is for this reason that their impulses get the better of them, they crave abnormal excitements, want to be on the go constantly, cannot be contented with simple and honorable home duties and finally merge into a condition where they have to seek the doctor or else go to a sanitarium. Now just consider for a moment some simple facts. You are taught, early in life, the necessity of exercising in order to develop and be able to control your muscles. You are told to “learn to control your temper,” but unless you are in perfect physical condition, with plenty of reserve nervous force, which is really will force, to use when you need it most, how are you to “control your temper”?
