Free throw and Talent shows?

So I have been yoyoing for a little while now(4 years) and I never really learned anything new but for some reason my clouded mind set told me I should enter into a talent show on post. I don’t know if I have stage fright because I have never done something like this and now I need to learn some new tricks or learn how to free perform. Does anyone have any tips to help me out? I am stationed at Fort Gordon in Georgia and I have like a week and a half before the show comes up and I don’t have any good tricks to use, or I don’t think they are all that impressive, so if someone could help me out it would be awesome, I don’t want to embarrass myself that much, Thanks.
