I spoke with many musicians when I visited the hospital I'm dealing with. I can offer two advices.
The first is avoid BCRich like the fucking plague, though that comes from my own experience.
The other, however, is both easy and difficult: Practice.
When I wasa free man I did not understand the word properly. Now I do.
When I first tried learning the guitar, I played maybe ten, maybe twenty minutes a week. After epilepsy hit, I understood what "I don't have enough time" really means.
Considering the mechanics of my seizures, I cannot do this myself, however, should I become a free man, I will properly execute what I call "operation musical monk".
I spoke about this with several musicians about this and we all agreed - if I'm insane and strong enough to huddle apart in my apartment and spent every damn second I have on practice and fucking around with the guitar, even ignoring the fact I'm bleeding (which has happened once), I would become "good" in no time.
The problem, of course, is the definition of "good". I'm a bit of an overachiever on certain things.
