'How do I get him or her to behave?' When I give a talk to parents, they usually want me to talk about discipline.
But I have to remind them about the cart and the horse. Or about the fact that a farmer would be foolish to look for a harvest if he had not done any sowing.
Discipline that is worthy of the name cannot happen in a vacuum. Of course you can set up your household with rules and regulations and insist on obedience. But there is a true saying which bears repeating: Rules without relationship lead to rebellion.
