I believe that all children are born motivated to figure out their world. They immediately begin to learn our language, discover how to crawl and walk and find ways to fit into the family structure. Nobody has to motivate them. They want to do those things for themselves. Unfortunately, it may be the parents who are trying so hard to help their children be successful.
Parents resort to lectures, rewards and punishments.
And children counter with a poor attitude. It's the ultimate power struggle. And no one is winning. It may sound overly simple, but my suggestion is to spend less time overseeing your child's efforts and more time talking to her. Set aside time each week to have a real conversation with her.
