If you can find some guys at a level similar to yours, nothing wrong with forming a "band" and honing your skills together. That's what most high school or garage bands are. You work at it together until you are ready for the big time of playing in front of an audience.

Just don't expect people to pay for you to play for a while :-).

What's good about a band is you HAVE to focus on entire songs, not just fragments.
