My 82 cents---------->Lack of communication, Individual goals are worlds apart, Schedules, lack of motivation by most or all of the members, but never at the same time, frustration, EVERYBODY is always the ONLY ONE who moves equipment and does EVERYTHING, the rockstar in the band always shows up just in time to play the gig, but never in time to set up and is the first to leave, and last but certainly not least...The lack, or refusal to give, comprimise and understand, that your band-mate is now dealing with some things that you were a month ago, when you couldn't understand why no-one understood....um, here we go with the double talk thing again.
