Remember that the subjective part of your mind never forgets.
The more you get into the habit of permitting your mind to flit, the less you will be able to remember. The best students are those who make their studies interesting. The best business men are the persons who take interest in their business.
Tie yourself down to everything you do.
And then, every once in a while, hold a mind review.
Think of the different places you have lived, what you did, the people you knew, what became of them.
Exercise your memory regularly.
Unless it is exercised, it falls into disuse—like an unused muscle—and becomes weaker.
Within a few weeks, you will be able to concentrate your mind on anything you do or read or say. That is practice of the right kind. It is scientific practice that considers your memory as a necessary part of your entire being.
And remember, that you should so concentrate on these lessons that you can repeat the thought, the ideas contained in them.
With this kind of practice, memory will become a strong asset with you—and it is a valuable asset, too.
