I understand fully the argument with regard to bettering ones self technically as a player and understanding theory etc, however one has to ask why you picked an instrument up as a kid in the first place? Is it because you wanted to be proficient in musical theory, and technically brilliant as a player? Or was it because the music you first heard stirred enough emotion inside you to make you say to yourself "I want to play music like that". For me it was the latter, and my only motivation to play today, some 30 years since I first picked up a Columbus Jazz for the first time, remains the same. Emotion, and love for music, of many different styles. For me, it's emotion and feel first, technique second, and theory some way behind that.
My lack of musical theory knowledge hasn't spoilt my love of music thus far, and my playing, as average as it may be, still makes me feel happy inside, which for me, is the [i]only[/i] reason for playing music at all.
Edit: not sure how much relevance this post has to the OP, sorry if I've wandered off topic, again.
