I don't know about you, but I have never liked being told what to do. I don't think I've ever met anybody who did respond well to that kind of instruction, even when the person in charge-a coach at sports, for example-clearly knew what he was doing if the message is delivered wrong. It doesn't matter if what you are saying is true, if it's not delivered properly. You can be the authority, but no one cares if you can't deliver your message in a way that others can accept. The fact that you have good prudent knowledge, the fact that you're correct, doesn't matter if not delivered properly.
