I have Vol. 1 and I just received Vol. 2. A grand master method, deliciously designed. A thousand thanks to him! The content of the book matches its cover, simple and perfectly balanced, neither too much nor too little. It goes to the essentials and personally, practicing it gives me great pleasure. I also use it as a work support for classes, this method is perfect!
