When I first came to my current teacher, he told me I needed to let go of everything I believe in and listen to him, because it would all make sense one day, I would be so glad I didn't argue..
I do ask questions, though... If they are good questions- involving practice strategies or little technical things im not sure of, FINE. he will happily respond. But, if he ties to teach me something new (especially if he is trying to break a bad habit of mine), and I keep arguing, subconsiously refusing to change, he will become very frustrated and the lesson turns into a session of cold shoulders and dirty looks..
I know everything my teacher does for me is benificial. If I need to be yelled at, he'll do it. If I need to be less cocky, he'll bluntly tell me. It's seriously like having my own Simon Cowell..
I love my teacher very much. The worst teacher is the kind that doesn't care about you or the music...just sits back and tells you how great you are- "ok, that sounds great, keep it up, Ill see you next week, that will be 24$".
In conclusion, Listen to the teacher..do everything they say, ask questions when you are confused, and if things dont go well- you aren't improving, for example,, maybe it's time for another teacher.
