I have to admit that I'm about to run counter to most of the advice on this thread. It sounds as if you're frustrated with him as a teacher. He may be a wonderful man, a wonderful resource and a wonderful connection but if you're not happy about taking lessons from him and feeling that you're not going in the direction you want to he may not be the best teacher for you at this moment. Keep with him if your options are limited and certainly keep him as a friend but also keep your eyes open for other opportunities for lessons that might suit you better.
