I think nervousness - a heightened sense of nerves and attention is a very healthy thing for a performer. It is an artificial environment that you are going into whether it's concert or recital, or stage. When I know something so well, I've done it so often, and you kind of walk out for Tuesday night's performance, or you feel like that, that makes me more nervous then being geared up. A little bit like race horses. In the same way that the horses are always difficult to get into that lineup, the worst time of my life is the 10 or 15 minutes before I go on stage.
