_e._ Have some one read you a sentence out of a book and you then repeat it. Do this daily, gradually increasing the length of the quotation from short sentences to whole paragraphs. Try to find out what is the extreme limit of your ability in this respect compared with that of other members of your family. Rule II. _Fix ideas by their associates._ There are other things to be remembered besides facts of outside observation. You are not one whose life is passed entirely in a physical world. You live also within. Your mind is unceasingly at work with the materials of the past painting the pictures of the future. You are called upon to scheme, to plan, to devise, to invent, to compose and to foresee. If all this mental work is not wasted energy, you must be able to recall its conclusions when occasion requires. A happy thought comes to you--will you remember it tomorrow when the hour for action arrives? There is but one way to be sure, and that is by making a study of the whole associative mental process. Review the train of ideas by which you reached your conclusion. Carry the thought on in mind to its legitimate conclusion. See yourself acting upon it. Mark its relations to other persons. Note all the details of the mental picture. In other words, to remember thoughts, cultivate thought-observation just as you cultivate sense-observation to remember outside matters. [Sidenote: _Three Exercises for Developing Thought-Memory_] To train yourself in thought-memory, use the following exercises: _a._ Every morning at eight o'clock, sharp on the minute, fix upon a certain idea and determine to recall it at a certain hour during the day. Put your whole will into this resolution. Try to imagine what activities you will be engaged in at the appointed hour, and think of the chosen idea as identified with those activities. Associate it in your mind with some object that will be at hand when the set time comes. Having thus fixed the idea in your mind, forget it. Do not refer to it in your thoughts. With practice you will find yourself automatically carrying out your own orders. Persist in this exercise for at least three months. _b._ Every night when you retire fix upon the hour at which you wish to get up in the morning. In connection with your waking at that hour, think of all the sounds that will be apt to be occurring at that particular time. Bar every other thought from your consciousness and fall asleep with the intense determination to arise at the time set. By all means, get up instantly when you awaken. Keep up this exercise and you will soon be able to awaken at any hour you may wish. [Sidenote: _How to Compel Recollection_]
