The student should begin by taking up some simple branch or certain subject of his work, and writing a short argument or essay upon it, using every fact that he can possibly command to convince imaginary readers of the correctness of his theories. Select a new subject and write something on it every day. This is merely mental calisthenics, and after a month's training the thoughts and the language will flow with a freedom that will enable the student to write just as he feels. [Sidenote: A booklet describing your work] It would be well to arrange an argument based upon each lesson separately, dividing it into short chapters. These arguments or essays should be logically arranged to form a booklet, with proper title, as such representative literature is vitally necessary to the growth and the success of your work. It will also be found that this will be splendid mental exercise, and will serve well in presenting your work, either orally, or by letter. [Sidenote: The personality of the writer] Every one should endeavor to be original in his literature; in other words, no special effort should be made to quote any "authority" or to copy the style of other writers. Put your own personality into your work, for the most successful writer is not always the one who uses the most learned, polished or scholarly language, but the one who can convey his thoughts to the minds of others in the simplest and the most comprehensive language. Language at best is but a vehicle for conveying the thoughts of one person to the mind of another, and while there are accepted standards in literature and letters, from which one should not make too radical a departure, yet the ability to present one's convictions, or position convincingly should be of first consideration. The most important thing in writing is to have something to say; then to say it so that it can be understood. VALUE OF EXPERIENCE Experience is the only method by which theory can be converted into knowledge. The best possible source of information, therefore, is personal experimentation. If the student should have any disorder, especially of digestion and assimilation of food, or elimination of waste, he should experiment upon himself along the lines laid out in this course. He should keep an accurate record of selections, combinations, and proportions of food, with results or symptoms. He may thus be able to arrange menus for himself, even more effective than those given as examples or guides throughout the course. If there are no personal disorders that will permit of such experiments, then they should be made upon some other person with whom the student is sufficiently familiar in order that accurate information concerning the results may be secured.
