Ask questions, meet dancers, and be part of the conversation.
I'm here and I'm in over my head. That goofy looking new guy who hangs around the edges writing everything down? That's me.
Don't be worried, stop writing so much down and actually go and do it. You'll screw up, and try it again, and screw up again, and then finally get it and it will be the best feeling in the world.
Just go have fun, push yourself to be in the center of the floor because you'll focus better since you won't be hiding in a corner, and just dance.
Have a great time! I'm so sad I couldn't go this year.
