In early childhood, time is long.Just worry about not using the wrong time.Now the situation is different. There are too many useful things and we don't have enough time.Just know that passion is coming, and when it knocks, your students won't have time to focus on anything else.It is folly to try to make learned men of your pupils when the periods of intellectual lull are so short and fleeting, and with so much to do.It is still your duty to teach him various subjects, but to give him an interest in knowledge, and methods of learning when that interest matures.Needless to say, this is the fundamental principle of all good education.
