Performing

For over a month I've been getting ready for a December 19 showcase.
Stage fright is my Waterloo, and it's a big one.
To get ready, I've been practicing almost every day. I've also been listening to a 30-minute motivational CD about performance anxiety, and I even made a four-minute CD of my own.
Every night I listen to each song I'll be performing to. I visualize the studio, the audience, and myself in performance.
It's hard (more like impossible!) to know how to tackle this.
I also read a book about performance anxiety. I thought it would be terrific because it purports to use a Jungian approach, and I think I have a Jungian outlook.
BUT. The book took an archeological approach to performance anxiety, viewing it as rooted in past trauma.
I think my performance anxiety is related to...well, I don't know.
I think I have trouble believing for real that I'm a dancer. I'm one of those people who read and go to libraries. I'm not a dancer. Not me!
I think I have trouble with the whole idea of performance. Why am I up there? To show what I can do? Who cares?
I don't mean that cynically. I just mean that "look what I know how to do" has to have pretty limited interest for people.
So I'm up there to entertain the audience. But what's entertaining about watching me do a foxtrot?
Again, I don't mean that cynically. I love foxtrot, it's my best dance, and I do it very well. And it's getting even better. But why would you want to watch it?
I have to find an answer to that question, program the answer into my body and my brain, and bring it to life in front of the audience.
When I've figured out how to do that, I think performance anxiety will be much less of a problem.
