A child will always tire of a toy when he no longer has any difficulty using it. He is like the 
boy with a bicycle; as long as he finds it difficult to avoid trees and to turn corners, so long will he 
spend all his spare time on it. But once he has thoroughly mastered it, he will only use it as a means 
of getting about, and not for its own sake. It is an unhealthy child who has no creative interest. Keep a 
child busy and he'll be happy, and conversely, a happy child will always be busy.
