Whaaaa he sure knows how to shatter our dreams!!! I know that feeling exactly - it has happened to me a lot too. You think you are so advanced...it sounds so smooth and sophisticated in your own mind. Now you truly made it! And then some advanced player pats you on the head and says "keep practicing and someday it may sound a little better"...
NOT FAIR!
I guess we have to accept we are eternal bloody beginners... at least now we can relax
