One of the most subtle foes of a good memory is procrastination.
Like conscience, memory can be dulled and almost ruined by continual
disregard of its suggestions. Failure to act when reminded ruins what
memory power you have and retards your progress and further development.
A Reminder picture will suggest an errand or duty one--two--or more
times, but there is an ever increasing lapse of time between each
reminder.
To Procrastinate--to put off doing the thing will dull the suggestive
power of the memory. It will clutter the mind with undone things which
will cause mental worry. It will weaken the will power.
To Act--to accomplish the thing at the first suggestion quickens and
improves the suggestive power of the memory. It clears the mind for new
thoughts and plans. It relieves the nervous strain and increases and
strengthens the volitional power.
It is the child's memory you wish to improve and this can only be
accomplished by his effort. You must help, of course, but do not do
too much, merely suggest. Get him to imagine and visualize his own
pictures, it will be better for him to make the effort than for you to
make it for him.
