If you worked on music every day for 3 hours, improving your production values and becoming a good sound designer, you could easily be OCR material in a year. Too bad that it's extremely difficult to be THAT motivated.
EDIT: I didn't take the compositional side of things into account, but I don't think it would make a huge difference. Composition comes pretty naturally to me just because I hear songs in my head all the time. I don't know if it's that easy for anyone else, but I digress. Compositionally, the only thing I really struggle with is drums.
