I heard about this book, and yes, reviews are really good, but i was too lazy to try it out, cause, when i try to do something about stutter and it doesn't work, it makes me feel hopeless, also i don't really like to read books, i get bored, and, from my experience about stutter, i know that no one can help you but yourself, of course, someone can give you a hand with this, but mostly it's only you, the way you think about your issue and confidence of course, sooo, the way this book works, i think it's effect of auto-suggestion, like, you read and your mind believes that it works, that way, it helps you to stutter less, cause, our issue is mostly psychological in my opinion, and this books helps to relief it, it's just my opinion, i might be wrong
