You took dance? That'll help you out with some of the footwork later on. I found that latin ballroom dancing with my girlfriend helped to get me more aware of what my feet were doing and improved my techniques.
Anyways as I said before, I was really shy before and after practicing Aikido for even a few short months I found my confidence had increased by a vast amount. So now, being put on the spot only really gets me when I have no idea how to begin a technique.
