There are three general rules that may be given in this matter of bestowing the voluntary attention in the direction of actually seeing things, instead of merely looking at them. The first is: Make yourself take an interest in the thing. The second: See it as if you were taking note of it in order to repeat its details to a friend—this will force you to "take notice." The third: Give to your subconsciousness a mental command to take note of what you are looking at—say to it; "Here, you take note of this and remember it for me!" This last consists of a peculiar "knack" that can be attained by a little practice—it will "come to you" suddenly after a few trials.

Regarding this third rule whereby the sub-consciousness is made to work for you, Charles Leland has the following to say, although he uses it to illustrate another point: "As I understand it, it is a kind of impulse or projection of will into the coming work. I may here illustrate this with a curious fact in physics. If the reader wished to ring a doorbell so as to produce as much sound as possible, he would probably pull it as far back as he could, and then let it go. But if ho would, in letting it go, simply give it a tap with his forefinger, he would actually redouble the sound. Or, to shoot an arrow as far as possible, it is not enough to merely draw the bow to its utmost span or tension. If, just as it goes, you will give the bow a quick push, though the effort be trifling, the arrow will fly almost as far again as it would have done without it. Or, if, as is well known in wielding a very sharp sabre, we make the draw cut; that is, if to the blow or chop, as with an axe, we also add a certain slight pull, simultaneously, we can cut through a silk handkerchief or a sheep. Forethought (command to the subconsciousness) is the tap on the bell; the push on the bow; the draw on the sabre. It is the deliberate but yet rapid action of the mind when before dismissing thought, we bid the mind to consequently respond. It is more than merely thinking what we are to do; it is the bidding or ordering the Self to fulfill a task before willing it."

Remember first, last and always, that before you can remember, or recollect, you must first perceive; and that perception is possible only through attention, and responds in degree to the later. Therefore, it has truly been said that: "The great Art of Memory is Attention. ''
