I read it about a month ago, seemed quite relatable and made sense. I do my best to practice everything as stated. It’s still early to say that it’s helping me since I haven’t perfected the ‘crutches’ but when I skip a day or two without practicing my speech gets worse. Also there’s a part about self-hypnosis, I suggest you watch YouTube for tips to make your own self-hypnosis recording. You don’t need any fancy music or audio editing, just a proper guidance will do good. Good luck! :)
