Query: Pick which exercises to use when you buy this bbok

I am a professional guitarist and guitar teacher. I just got this book and I think its great and can really improve your playing. Its also a HUGE book with many pages. I am posting this review so anyone who buys it knows that one good way to approach it is to pick the exercises that you need to improve your playing. You don't necessarily need to start from page one and work your way through to end, and you definitely don't need to do every exercise in this book. There's a wealth of knowledge here, but if you buy this book, don't let it overwhelm you - take what you need and it allow it to improve your playing, and leave the rest alone.
