It is always absolutely necessary for the hypnotist to be able to fix his mind wholly upon one train of thought. Many fail in their first attempts, because they allow a multitude of thoughts to flit through the mind while conducting experiments. For instance, they are all the time wondering if they actually will succeed, and think what effect their success will have on others, and imagining what possibilities the future might bring to them if they should succeed. It is surprising what a multitude of varied thoughts the mind is capable of entertaining, seemingly at one time, and still be striving to perform some special work.

Here, again, practice is valuable. The student of hypnotism should, by all means, learn to concentrate his thoughts, for in his work, as in every other line of work, an ability to do so is invaluable. To keep the mind on one thing may not be an easy task at first, but it must be accomplished before success can be attained.
