Good thing you posted that Vinnie
I had the same problem for a while, but I checked around the boards some and I've gotten my show down some, but I'm still working on it. The main two things I've found out so far:
Slow Down: Go really, really, really..., slow. I did a show once at 'normal' speed, and I lost the audience from the beginning. I slowed down and it got better. I slowed down some more and it got even better.
Warm Up: This was sluggo's tip for me. Don't start with saying "Ok here's my first trick..." Warm up the audience some. Joke around with the kids, get them intested in you before the magic starts. You should talk with sluggo for some more on this, he really helped me out!
I still don't perform for money, I do shows at elementary schools on reading nights and such, plus for churches, and it's getting better with each show. Don't rush into getting paid, because then you have to be GREAT. Have fun with it at first, the money will come later when you aren't all that concerned with it I bet.
