Everything which you wish to remember does not take form in a definite object which can be visualized and often presents a more difficult problem. Fortunately the mind only requires a hint or suggestion to start the Law of Association into operation which will bring the thought not in itself easily pictured. As the child progresses his imagination will find many original ways in which to create Reminder Pictures to aid him in remembering abstract ideas. This ability will not come except by practice and effort; if he is allowed to consider the remembering of abstract ideas an obstacle to success it will be so; but if he tries to master these he will find it is not difficult to create a picture which will remind him of what he wishes to remember.
