At one point or another, you must realize that people suck. It isn't about finding people who don't, because everyone does. Me, you, everyone. It's about sorting through the shit and focusing on music, not eachother. If they suck at music and they are dicks, throw em out, unless you have some connection to them and need em. If they are nice people, you should bear it out.
I really kinda suck at trombone right now. I've been playing about 2 months now, I can only get two octaves of a few scales, and I can't roll my r's, so my tonguing is limited greatly. My friends know this. I'm still in a ska band, because I know it will improve my playing, and they know it, too. My airflow has increased greatly, and I'd say I couldn't reach those octaves without practice in a playing environment.
People suck, but they get better. Give it time.
