Me? Or the book author?
In case I violated forum etiquette or something I'm sorry!
The book author is a guitarrist and he writes from his perspective as a player of that instrument, but I think there are many things in there that relate to music (and even life) in general.
I'm new to music (bass, three months) but this book has already changed the way I approach my practice sessions. I already passed it to my 16 y.o. sold who is thinking on going to college to study music.
