Seriously, the clearing process is the easiest time you will have as a medic. You are out of school and no longer considered a "student". You are no longer trying to demonstrate that you have a clue... you proved that by earning your patch. Now comes the time to reflect on what you have learned and apply it to the real world for your agency.
Concentrate on treating your patients with care, your coworkers with respect, and learning all you can from your FTO about how things work in your system. Nobody expects you to be perfect on day one, don't be afraid to ask for help or opinions, that's why you're clearing.
Each call you run will add to the data base building in your head of the one thing you can't buy in medicine... expierience. Whether you nail it or fumble it every call is a learning process and if you remain humble, keep an open mind and do the best you can on every call you will be fine.
Good luck and have fun you worked hard to get that patch!
