Oh yeah... it's a great hobby for enjoyment, enhancing your sex/party life etc but by my calculations, 11680 hours of practice are necessary to professionally make money from it - or 4 hours a day for 8 years. I know many people make cash after having barely an 1/8 of that, but that's what I expect my local guitarhero to have under his belt. So if you're thirty, you can count on reaping the benifits when you're 40 or so, about a decade.
