For your child, this means that you need to convince him that there is a better way to look at and react to a situation than what he has shown you. He needs to hear what you are saying, maybe even see it, and then accept it if a better behavior is to occur. But you must realize that new thinking cannot occur easily, because your child is not a blank slate. He already has competitive version of your idea. Different stories and interpretations are present in him that will compete with your new story or mindset. If the new mindset or thinking is to succeed, it must replace, suppress, complement, or outweigh every other story or competing version or idea. Only the most powerful argument will win out. Your prior history with your child is a very powerful force in this equation. All previous unproductive discussions and interventions that you have had with him will make your job that much harder, and must be replaced as well. To deal with these factors, you must be persistent, stick to the point, not allow irrelevant items to be brought into the conversation, and, finally, provide the reasons for the new thinking.
