Education to become a master storyteller

In an effort to take my writing to the next level, I purchased the book, "The Anatomy of Story:  22 Steps to Becoming a Master Storyteller," by John Truby.  He is "one of the most respected and sought-after story consultants in the film industry . . ."  I have heard a lot about him, and watched some videos put on by Film Courage about his techniques here.  It had some good information, but a lot of it was generalized, so I bought the book to get all the details.  I'm hoping to take my writing to the next level after this.  We'll see how it goes.
