He needs to expand his horizons, increase his vocabulary, modify his delivery, make sense every time he speaks. After all he is being watched/listened to very carefully by everyone in the world. He could use some shaping up, thinning out, working out. He could go from inadequate to eloquent if he would only admit his inadequacies and study real hard and listen real hard and read a lot. He can learn to be better. He can't do it on his own though. He needs professional help.
