purpose, especially at the moment he conceives it. We remember
only that which makes a deep impression, hence we must first
deepen our impressions by associating in our minds certain ideas
that are related to them.

We will say a wife gives her husband a letter to mail. He does
not think about it, but automatically puts it in his pocket and
forgets all about it. When the letter was given to him had he
said to himself, "I will mail this letter. The box is at the next
corner and when I pass it I must drop this letter," it would have
enabled him to recall the letter the instant he reached the mail
box.

The same rule holds good in regard to more important things. For
example, if you are instructed to drop in and see Mr. Smith while
out to luncheon today, you will not forget it, if, at the moment
the instruction is given, you say to yourself something similar
to the following:

"When I get to the corner of Blank street, on my way to luncheon,
I shall turn to the right and call on Mr. Smith." In this way the
impression is made, the connection established and the sight of
the associated object recalls the errand.

The important thing to do is to deepen the impression at the very
moment it enters your mind. This is made possible, not only by
concentrating the mind upon the idea itself, but by surrounding
it with all possible association of ideas, so that each one will
reinforce the others.
