Of all the traps, distractions, and delaying maneuvers life in general (and music in particular) can hang you up in, "if only" is one of the slyest. "When I learn this song, buy/find this ax", etc., is difficult stuff. Almost as silly as,"If I think hard enough, I can solve this." I don't know a way out, though. Might as well play, while we're waiting.
