In the life of children there are two very clear-cut phases, before and after puberty. Before puberty the child's personality has not yet formed and it is easier to guide its life and make it acquire specific habits of order, discipline, and work: after puberty the personality develops impetuously and all extraneous intervention becomes odious, tyrannical, insufferable. Now it so happens that parents feel the responsibility towards their children precisely during this second period, when it is too late: then of course the stick and violence enter the scene and yield very few results indeed. Why not instead take an interest in the child during the first period?
