Use the Hitching Post
When listening to instructions, or a lecture, in which there are different points which you wish to carry away and later recall accurately, use the Hitching Post idea. Run over a series of words so as to be sure that they will come readily when wanted. When a point is made which you wish to remember, transfer the thought into a quick visual impression, and Hitch it to the first object of your list. When a second important point is made, make a visual impression with the next object. Make your picture strong by exaggeration and motion, and be sure that you photograph each one.
In this manner you can file away any number of points. As soon as the lecture is over review the pictures, see each clearly a second time. If you have trouble recalling one make the picture stronger so that you will recall it more easily next time. Review the entire list of points visualized with the different Hitching Posts. If you wish to fix them in mind review them several times in the next few days, so that you make a permanent impression of them.
