I don't think it's a question of possibility at all. Having talked to a lot of the people on here I've met some very talented and knowledgeable people here and some that want to take music further than the garage. I, myself, have plans on taking my skills as far as I possibly can and don't doubt for a second that I'm going to be "huge" some day. Some people here treat playing like a hobby, others treat it like it's their life. I read on here about people that go weeks (dare I say months) without playing and I can't help but wonder "why". I've gone maybe 2 or 3 days without playing and found that to suck too much. I often feel pain at work because I came up with an idea and can't wait to go home and try it out. I don't care what happens, I am going to make it somewhere vital to the world in music. No one can stop me.
