I'm not an instructor, just a participant. My only real input (and I think someone else said it, too) is this:
Just hold it all loosely, and remember that just because you start a course of training, or teaching, it doesn't mean you can't quit at any time if you discover you don't like any of the effects of it in your life.
Just stay in touch with how you're feeling about it all, and go with what gives you energy and satisfaction. If it stops doing that, consider what change you need to make at that time.
