I find the more I study double bass, the less I can deal with the rock musicians I was used to playing with. I just walked from one 50's style rock/swing band because the sloppy slacker approach of the band just drove me crazy, and now the same thing is happening with my string band that I very much enjoy. The further I get away from straight-up rock bands, the more I find the terms rock & musician to be two words that rarely justify being put together now. Really feel like I'm outgrowing everything I used to do in bands, and I'm far (very far) from considering myself a good upright bassist. Funny part is the more I get frustrated with others, the harder I want to work to become better and more varied in my own abilities.
