Well, it would be my advise that you give up that dream at your first opportunity! Playing in a band usually means working at a job/career all day to make enough money so that you can play in the band during the evening hours ....and playing to people who really don't listen and a good jukebox would serve just as well.
Check out other bands in the area, talk to them, ask them about their dreams of making it big. Then check out the rate of those bands making it big. It's sorta' like little kids wanting to be pro football players .....how many of those kids actually make it to the top of the heap? Odds ain't good, are they?
Hey, think about it .....how come there's only a few OLD bands in the world? And if that's true, what happened to those bands when they were younger?
Go to college, learn as much as possible so you can earn enough money to LATER play in a band for your own enjoyment and pleasure. Don't do it the other way around or you'll be on welfare most of your life.
