However, I think the opposite situation is also wrong -- playing in a band just because you are very good friend with the other members. I was stuck in this kind of situation for 3years, and the results are that I basically wasted my time. In this band no one really would bother practicing at home except for me, and in cases when we could not practice for 2 or more weeks due to school, exams the band just did not progress. One day I just said:"Look, guys, I'm leaving, It's obvious that my vision and your vision of the band are totally different". I only regret the fact that it took me THREE DAMN YEARS to realize that.
