I'm self taught, never used a book & never had any interest in the whole YouTube thing.
I bought a few books over the years but never got on with them, just found it too much like being back in school.
Apart from the first few years when I started playing when I was obsessed with it I've always been very lazy when it comes to learning stuff. It's the main reason I could never play in a covers band, having to sit down & learn a load of songs is my idea of hell.
