Thanks everyone for the responses!

I really do recognize the motivational value of performances, so I don't mind paying for it...if I'm actually ready! Right now I'm leaning towards no, but I'll have a heart to heart with my instructor next week. The truth is, I don't know if I'll ever actually feel prepared...even in 5 years! I have such respect for the art of dance, and I don't want to debase it by doing a lousy performance.
