I remember someone telling me that George Lynch once said he heard B.B. King say something that instantly improved his guitar style. It went something like this: “If you play a wrong note, play it again like you mean it and it’ll sound like the best note you played all night." The dubious origins of this gem aside, I've always found this to be an almost religious concept to strive toward, where any note can work anywhere if it is done with purposeful conviction.
