The wise student will acquire a great control over his emotional nature if he will re-read and study the above statements and quotations until he has grasped their spirit and essence. In those few lines he is given a philosophy of self-control and self-mastery that will be worth much to him if he will but apply it in practice. Patience, perseverance, practice, and will are required, but the reward is great. Even to those who have not the persistency to apply this truth fully, there will be a partial reward if they will use it to the extent of restraining so far as possible any undue physical expression of undesirable emotional excitement. Some writers seem to regard capacity for great emotional excitement and expression as a mark of a rich and full character or noble soul. This is far from being true. While it is a fact that the cultivation of certain emotions tends to create a noble character and a full life, it is equally true that the tendency to "gush" and indulge in hysterical or sentimental excesses is a mark of an ill-controlled nature and a weak, rather than strong, character. Moreover, it is a fact that excess in emotional excitement and expression tends toward the dissipation of the finer and nobler feelings which otherwise would seek an outlet in actual doing and practical action. In the language of the old Scotch engineer in the story, they are like the old locomotive which "spends sae much steam at the whustle that she hae nane left to gae by." Emotional excitement and expression are largely dependent upon habit and indulgence, although there is a great difference, of course, in the emotional nature and tendencies of various persons. Emotions, like physical actions or intellectual processes, become habitual by repetition. And habit renders all physical or mental actions easy of repetition. Each time one manifests anger, the deeper the mental path is made, and the easier it is to travel that path the next time. In the same way each time that anger is conquered and inhibited, the easier will it be to restrain it the next time. In the same way desirable habits of emotion and expression may be formed.
