Unlike a mechanical device that eventually wears out and must be
replaced if it is used continually and consistently, the mind grows only
stronger when it is active. The more you exercise and stretch your
brain, the more proficient it becomes. Disuse, however, will have the
same effect upon your mind as it will upon a machine. The most
intricate, most powerful machine in the world and the greatest minds
will rust away unless they are used.
Unless you manage your schedule to permit time for study and learning,
it is easy to yield to the temptation to spend your free time in
thoughtless, mind-numbing, escapist pastimes. Relaxation is important,
but so is gaining new knowledge. Make sure your daily schedule includes
an allotment of time for both.
