The greatest lesson of education is thought. The thing you should
be striving for and working toward is the ability to think clearly,
logically and deeply. One of the greatest aids is the knowledge which
is stored in your brain and which you are all able to recall at will.
Your brain is not like sticking plaster, it is like putty; you must
make an impression of the things you wish to retain. To make these
impressions will always require an effort, no help will ever be devised
which will enable you to remember without effort.
The ideas given to you in this book are aids, and you should become
able to use them as such. The principles of memory are scientifically
accurate and you need to become familiar with them and to use them to
add to your success in study and progress.
Do not be like the carpenter who "is too busy to sharpen his tools," or
like the drowning man who refused to grasp the rope because he feared
it was not strong enough.
Use every idea that proves helpful and apply it in every possible way.
There is no intent to give here all of the applications, but merely
to give principles and to suggest one or two ways in which they have
been used. The applications that are of most value to you are those you
make for yourself. The principles will cover every need, if you will be
resourceful in their use.
