Working as a private guitar teacher for over 15 years, I have seen thousands of guitarists... Both beginners and quite “experienced”. Both absolutely mediocre and incredibly gifted. And during this time, I practically never came across guitarists who would not make the mistakes that will be discussed in this small book... And by making these mistakes, you initially follow the wrong path, which will lead you in a few years only and exclusively to the teacher who you will have to unravel a huge pile of problems with both your hands and your thinking, which you have valiantly “earned” for yourself...
