What most impedes mental progress in children is the constant dispersion of their thoughts. Their thoughts flutter hither and thither like butterflies and they have to make a great effort to fix them. Yet this capacity is latent in them, for when you succeed in arousing their interest, they are capable of a good deal of attention. By his ingenuity, therefore, the educator will gradually help the child to become capable of a sustained effort of attention and a faculty of more and more complete absorption in the work in hand. All methods that can develop this faculty of attention from games to rewards are good and can all be utilised according to the need and the circumstances. But it is the psychological action that is most important and the sovereign method is to arouse in the child an interest in what you want to teach him, a liking for work, a will to progress. To love to learn is the most precious gift that one can give to a child: to love to learn always and everywhere, so that all circumstances, all happenings in life may be constantly renewed opportunities for learning more and always more.
