Along with the growth of the power of observation the will for progress and perfection must also grow. This will should be instilled into the child as soon as he is capable of having a will, that is to say, at a much earlier age than is usually believed. In order to awaken this will to surmount and conquer, different methods are appropriate in different cases; with certain individuals rational arguments are effective, for others their feelings and goodwill should be brought into play, with yet others the sense of dignity and self-respect. For all, the most powerful method is example constantly and sincerely shown. Once the resolution has been firmly established, one has only to proceed rigorously and persistently and never to accept any defeat as final.
To avoid all weakening and backsliding, there is one important point you must know and never forget: the will can be cultivated and developed just as the muscles can by methodical and progressive exercise. You take one little thing, something you want to do or don’t want to do. Begin with a small thing, not something very essential to the being, but a small detail. And then, if, for instance, it is something you are in the habit of doing, you insist on it with the same regularity, you see, either not to do it or to do it—you insist on it and compel yourself to do it as you compel yourself to lift a weight—it’s the same thing.
You make the same kind of effort, but it is more of an inner effort. And after having taken little things like this—things relatively easy, you know— after taking these and succeeding with them, you can unite with a greater force and try a more complicated experiment. And gradually, if you do this regularly, you will end up by acquiring an independent and very strong will. You must not shrink from demanding the maximum effort of your will even for a thing that seems of no importance, for it is through effort that its capacity grows, gradually acquiring the power to apply itself even to the most difficult things. What you have decided to do, you must do, whatever the cost, even if you have to renew your effort over and over again any number of times in order to do it.
