Query: Even an non-idiot might have difficulty wading through this

I've had this book for 3 years now, and at the same time I've been taking weekly ballroom dance classes. I thought that as I got more hands-on instruction, I would feel more comfortable with the instructional part of the book. I never did. Now that I am far more advanced than what is taught in the book, I still feel a bit confused trying to figure out what the author trying to teach. OK, some maybe I'm an idiot, but if I am, then this book should be geared to me. If there were an accompanying DVD, then I think it would be much better.
