There are any number of these dreads and, almost needless to say, all of them may interfere with health and the pursuit of happiness. I have seen men and women thrown into a severe nervous state with chilly feelings and cold sweat as the result of trying to overcome one of these dreads. They make it impossible for their victims to do a great many things that other people do readily, and sadly hamper their wills. There is only one way to overcome these dreads, and that is by a series of acts in the contrary direction until a habit of self-control with regard to these haunting ideas is secured. All mankind, almost without exception, has a dread of heights, and yet many thousands of men have in recent years learned to work on high buildings without very much inconvenience from the dread. The wages are good, they _want_ to work this way, and the result is they take themselves in hand and gradually acquire self-control. I have had many of them tell me that at first they were sure they would never be able to do it, but the gradual ascent of the building as the work proceeded accustomed them to height, {26} and after a while it became almost as natural to work high up in the air as on the first or second story of a building or even on the level ground. The overcoming of these dreads is not easy unless some good reason releases the will and sets it to exerting its full power. When this is the case, however, the dread is overcome and the brake lifted after some persistence, with absolute assurance. Men who became brave soldiers have been known to have had a great dread of blood in early life. Some of our best surgeons have had to leave the first operation that they ever saw or they would have fainted, and yet after repeated effort they have succeeded in overcoming this sensitiveness. As a matter of fact, most people suffer so much from dreads because they yielded to a minor dread and allowed a bad habit to be formed. It is a question of breaking a bad habit by contrary acts rather than of overcoming a natural disposition. Many of those who are victims have the feeling that they cannot be expected to conquer nature this way. As a result, they are so discouraged at the very idea that success is dubious and practically impossible from their very attitude of mind; but it is only the {27} second nature of a habit that they have to overcome, and this is quite another matter, for exactly contrary acts to these which formed a habit will break it.
