Wow, I can't believe I just read this whole thread
It's really interesting to see just how much thought goes in to some of these posts, and as someone (or several someone's) stated, jazz is more of an intellectual style of music ... that is, when you take the time to study it and analyze it
I was very fortunate, I started my playing in the jazz world and learned by listening and feeling the music, not by analyzing it. Frankly, I don't think I ever did analyze what I was playing while in the somewhat early stages of my playing, and I certainly do not analyze now after 44+ years (and I'm not saying that this is a good thing

).
To be fair, my schooling was at a world renowned highly regarded institution, and I spent many years analyzing classical music, so undoubtedly much of that knowledge found its way over to my jazz roots. But to me, jazz is a feel and groove, not a mechanically-learned series of phrases/patterns .... of course, note selection/use is absolutely critical, but it needs to come from deep inside. I'm not sure how to translate that to a young cat just starting to play the bass. I'm not thinking dorian or mixolydian while playing, I'm just playing .....
Props to all of the posters in this thread for their input, some very insightful things were posted here, even for an old -timer like me. But to the young player who started this thread, don't be discouraged ..... give it some time and you'll begin to develop the feel. And listen to and feel the music
