Nervous

So in about an hour I will be sitting in a interview for a job at a new school in my county. Its not that I am trying to get into a new county, it's basically like making a lateral transfer. I am a little nervous how i come across because sometimes I not sure if I come across that well. I have been up for about two hours now and am just exhausted. I really hope I get this because I think it is an amazing oppurtunity to be on a team that is the first faculty of a brand new school. I would love this and think it would help me grow professionally as well. We shall see. Cross your fingers.
