Man, there's too much. I don't know what to tell you, maybe a few things that comes to my mind. Stuttering is a system, it's a system that's constructed of parts that influence and are influenced by each other. That's the John Harrison's stuttering concept. Stuttering is not about speech, uttering words. Yes, there may be some components of neurological, genetical basis but that's just a contributing factor not the cause or primary factor. And that factor can be more or less. It all depends, because stuttering is kind of a habit and everyone is different. You know... Stuttering, fluency is about letting go. To let the subconscious mind take over the process, the speech, because that's so complex process you cannot consciously control. Etc etc. It basically gave me the answers I needed, the understanding, showed my I can become fluent or significantly improve and how to do that.
