I'm not afraid of being a musician. I just pick up instruments and fool around. I can think of scarier things to do. /sarcasm
I don't factor in performance or what I'm supposed to doing with it as a career. Not out of fear.. it's just not what it's about. I was talking to Tallulah about this other day (that she agreed with as well). I made a joke that I barely even play standing up.. I barely put a guitar strap on. That whole other aspect is an afterthought.
When I do think about it however, it's not really the direction for me anyways. I don't know where music is going (industry-wise) these days. People barely even buy music these days. Your bread and butter is touring now (hard work, for sure). Unless you skyrocket into Lady Gaga territory or something. It's really polarized as far making a good income out of (you might be lucky if have some niche though). Some of my favorite bands though contain people who actually have dayjobs and other side projects. Some are only making 30 grand in their best year, strictly from music. There was an NPR show on this the other day actually.. can't find a link.. but I knew about this anyways. It was already heading in this direction by the 90's. There's a well known article by Steve Albini (recording engineer/former front of Big Black) where he pointed out some other issues (before piracy was even a problem): The Problem With Music
