Should I be a musician one day?

Im 14 and I just cant stop thinking about music. My head buzzes with melodies and rhythms all day. Every time I see The Strokes play or some other band, I picture it as me. I've always wanted to be just like them. You have no I idea how much rock band and GH world tour I play. I have a whole book with like 45 pages of songs, melodies, rythms, etc. I memories the lyrics to ALL of my favorite songs. Is this obsession, or a desire? Whatever it is, It's me wanting be a musician one day, a rock band, just like The Strokes, U2, Green Day, Billy Idol, or The Ramones. Should I fu**ing go for it?
