I won't be here on the 15th, but happy early birthday, Satch!

I'm having a bit of a problem with my band. I'm 15 and I really have fun with the guys, but my drummer doesn't want to go pro with what we have going. He wants to focus on his "plans" for after high school instead of what he's doing now. My bassist and I are considering moving on because this is going nowhere and music is all we have. Should we just move onto another band or do you think we should stay?
