May be that might be the case with J Millers problem. It is just a thought.
Leaders are only leaders for as long as they can lead.
At ANY given time a horse has the right not to accept me as leader for any reason. If I do not have the leadership ability to get him to comply with what I want, I have lost my ability to lead. Because I understand the nuances and the sequence of herd dynamics better than he does, I am able to get him to comply ANY time he changes his mind or has second thoughts. As I have said, the horse has the right to change his mind, forget, whatever - this is a no force technique. I can do can stop him from changing his mind if he wants to for what ever reason.
