First off, I don't even know if this belongs here or in music fans, please move it accordingly admins.

So far, I am sure I want to be a full time musician. This is where my pleasure lies, mainly composition. I've decided to take this step beyond before it's too late, I really want to make a living out of this, as a soundtrack composer.
The whole thing might seem easy for me now, but I know nothing about what does it mean to become a part of the business. Not even becoming famous atm, just making a living out of it.
I realize it's not going to be easy at all, specially since I'm not familiarized with anything that has to do with having a job at all.

There are a couple of topics I'd like to talk about on this one thread:

  • Music Production

    What could be a good starting point? I'm afraid this might be closed due to it being opinion based, but there must be some kind of consensus on where should a producer begin at. If I'm going to be a part of the business, I might as well know all of this stuff rather than being mediocre at it.

  • Theory

    This one's confusing. I've taken my decision for a long time now, I DO want to learn theory, and I currently am, mostly self taught (I have a teacher, and he's helped a lot, but most of the work [as it should] lies on me and some Wikipedia articles (is that a nice source for this kinda things btw?).
    I say it's confusing because you see all these famous guys who are self-taught and don't even know how to read music, playing in humongous bands. My best example for this would be Steve Howe from Yes, who has claimed numerous times that he's never known how to read music, yet he's made amazingly complex things. Is it necessary to be a theory erudite to be considered a professional?
    Now, in contrast...

  • Technique

    I'll say it, I'm an average guitar player. Not the best one, not the worst one. In fact, my teacher has told me a couple of times I'm his most perseverant student, and the one who has shown most capability on the instrument. Doesn't mean much tho, I can move myself around modes kinda smoothly, and throw some extended chords here and there, but nothing too special.
    Thing is, I never truly aimed to be a technical player. You see all these Malmsteems, Vaughans, Satrianis, Petruccis, Vais all over YouTube, Facebook, whatnot. It was never my thing, I respect them all a lot, but it was never my aim.
    That's not to say I wanted to be stubborn and mediocre, not at all, I wanted to be a capable player, someone who can play over whatever's given to me, be it in a classical, jazz or rock context.
    As I've said, my main focus has always been composition, and I want to make a living mainly out of that one aspect.
    In short, technique has never been my strenght, how much does it influence the business side of things?

  • Whatever else

    Right now I'm really worried about this whole thing, "what if I have to downgrade my dream job to a mere hobby?" "what if I don't make it big?" "what if I end up being bad at it?" I just need as much advice as possible in every possible context, please, this could also help those who are unaware of these things.
    Thanks to whoever answers, it is truly appreciated.

    • Hi Renzo. Unfortunately as is this question is way too broad and goes in way too many directions to be contained in one question. Also a lot of what you're asking is really opinion based and some of the subquestions have even already been answered. Please break up the main questions here and try to focus on object questions. – Dom Sep 20 '16 at 0:31
