I have tried to tell you how necessary it is that all your organs should be kept in perfect condition by knowing what they are, and what they do and how to help them in doing the right thing. Your teachers are constantly at you to make you train your memory, to keep your mind upon your studies, or else your employer is nagging you to pay more attention to what you are told. And how many of you try to do all this and do not succeed! “Train every faculty, build up your abilities;” do this or don’t do that; always something is dinned into your ears about what you should do to improve yourself. But the one force, THE power which is at the bottom of every impulse or act, nerve activity, is left unmentioned as a force to be trained first, always and last of all the forces in your body. “She has such a bad temper” is a remark we hear time after time. “If she would only learn to control her outbreaks; don’t get out of temper,” and similar expressions are only too frequently heard in homes and at school――everywhere. No wonder the helpless girl becomes discouraged and disgusted when she is scolded for petty explosions which she would gladly know how to stop. A girl without a temper doesn’t amount to much. It is a proper attitude of revolt against personal wrong or injustice. It is the birthright of every normal woman. It belongs to her protective instincts. And what is temper? Just the explosion of a highly nervous temperament. Explosion, mind you, not a decent expression of righteous indignation. The difference is that one is uncontrolled nervous force, the other is the same expression of nervous force held in check, governed by long training and handled for some forthright deeds. It is the preserving of this nervous force so as to be able to utilize it for some valuable work, that makes the difference between wasted energy and useless efforts and applied energy with useful results. The nervous force in woman, including the brain, is the last to become fully developed, but it should be the first to be considered in your training. It means self-control, and there is no better evidence of good birth, well-poised personality and perfect physical health, than control over one’s impulses and words. A girl with these qualities will soon get a husband who will be kept as a husband.
