At the gig, I forget it all and go for it. So I am happy at that point. A lot of what I am unhappy about comes from my own personal laziness. I know the theory and I know how to learn by ear and apply all this stuff - I just need to get off my duff and do it. Everyone can always improve, but you have to be able to enjoy the moments in between learning and play for fun.
