I'm glad you are recommending a book that actually worked for you. My instructor states I am his best student ... but only because I'm the only one of his students who actually practices.
I'd rather gain higher acclaim than that! I think many people struggle with the necessary synergies between practice and performance and the translation from the former to the later. I'm about to buy this book and give it a shot as I'm always open to new ideas, especially if someone else finds them effective.
Besides, I may well start teaching guitar after I retire from Nursing. I'm already a nursing educator, so I have all the teaching theory down, but music focused stuff like this sounds wonderful.
