U.S Express @ Tunnel hill, GA tomorrow

Hey room, I'm looking for some personal advice for orientation tomorrow. I have read a lot of threads and orientation story's which can either scare you off or give you hope but a little advise can go a long way. I've pulled a lot of strings, scraped up a lot of change to get through school and make it this far and I just do not want to make any rookie mistakes and get sent home without a job. Anything would help thanks
