Give up on this guy, he isn't going to listen to anyone. He obviously knows everything and can be taught nothing! Quite frankly, I would't want him in my club. His type of immaturity is not needed.
Let him go fly on his own and eventually he will get what is coming to him. After all, he can't say he wasn't warned. Nice try guys, but you are risking carpal tunnel problems trying to convince this guy of anything.
