Re: Being your own teacher
I think what you are talking about is the point at which you become A teacher. When you teach the system from your perspective, and not just parroting what your teacher said.
I've watched lot's of Aikido practitioners take over one of their teachers classes. All of them sound like a little copy of their teacher. Eventually most of them, over time, start to get their own voice, and their own answers. This is when you really start to become a teacher. When you teach Aikido (or whatever) from your personal experience and your not just spouting off what your teacher told you.
