Attendings and current PAs, what would you tell a new grad PA coming in to the ED?

I was an RRT certified in trauma and critical care prior to PA school and knew before ever beginning that I'd end up right back in the ED. So, the atmosphere isn't new to me, but the responsibility and new role is scary, I'll admit. Thankfully, I scored a job at a facility in my incredibly small and rural town and clicked well with the staff during a rotation there. Even as a student I had more than my fair share of sutures, i&ds, intubated a few, put in a chest tube, central lines, it was incredible and the attendings were happy to help and teach. Well, most of them lol. The MDs do manage most of the critical one on one's that come through, but the PAs still manage pretty sick folks which I'm happy for. I want to learn and not become complacent, but the closer my start date nears, the more I get a little nervous. Any advice would be appreciated. Thanks for any responses!
