I loved that guy. I think he understand stuttering better than most of us. Stuttering is not a single way situation. Is a multiple system that interact constantly with each variable creating an unique organism for everyone. We have to deal with the whole situation to change ourselfs. Most program focus on one variable. They are not wrong just incomplete. Another thing I love about the book is that he changed the word stuttering for holding back / blocking. It is brilliant. When we said holding back we are trying to avoid something to happen. Same as blocking, we are blocking something. Stuttering give zero information besides the visible aspect of it. Only the change of words get us closer to understanding our stutterinig hexagon system.
