When i comes to surpassing your teacher I think people who teach usually consider it as a possibiliy. My piano teacher once told me she thought the beginner was more interesting than the master because you could never be sure what a beginner ws going to do or how far they will end up going. I was taught guitar by a friend of mine and had several people tell me I would never be as good as he was. When I told him this he said '**** that, I'm going to make you as good as me.' How I compare to him these days I dont know.....for one reason or another we havent played together for over 2 years. Not that i like to compare myself to anyone else......I think I'm a differet kind of guitarist to my friend now, I went off on metal which he was never a big fan of but I still play the other styles we went over together and I will always have what he taught me. You can always tell a good teacher from the way their student plays.
