Heritage Fair

I am soo scared!  It is going to be heritage fair this week and my group and I only had 2 weeks to do the whole thing!!!  What if I blank out in front of the judges?  What if I fail my group from lack of knowledge?  I must calm down!  If I calm down, everything will be absolutely fine!  I'm sure of it.  Keep it cool and just have fun!  What's the point of doing something if you can't enjoy it?  Right? I'm sure of myself of course I'm right!  Ok...PeACe :)
