Besides being the strongest of all the senses, sight is the most
accurate. Psychological tests have shown the eye to be mistaken only
eighteen per cent of the time, and the ear, which is the second sense
in strength, is mistaken thirty-four per cent. Note that your sense
of sight is especially endowed with the power to make the strongest,
and at the same time, the most accurate impression upon your brain.
The first step in memory improvement is to learn the proper use of
this sense in impressing upon the brain those things which you wish to
recall.
=For the purposes of memory, to see a thing once is equal to
having repeated it eighteen or twenty times.=
