Don't knock. I could have used some strict parenting, to be sure. Or any parenting, for that matter.

It's definitely a satisfying hobby, even if you only play yourself. Nothing quite like being able to play something at speed that you have struggled with for weeks. But it's also frustrating, especially if you're trying to do it without a teacher (and run screaming from anything to do with notes or theory). Too much for my frayed mind these days. Guthrie Govan likes to say that he's saving classical guitar for prison. Pretty much my feelings on the matter.
