Put on a flight or two of one of your other planes first. Preferably of one you are VERY comfortable with.
DO NOT get in a hurry.
If ANYTHING is not right with the plane do not fly!!!
Fire the engine and let it warm up, then shut it down and walk away for 5 minutes.
After you have calmed down for five minutes, go back and fire the engine again and taxi up and down the field a couple of times to get used to the ground handling. Is everything OK? If yes, taxi back and shut the engine down and relax for a bit.
After you have calmed down again, go back and refire the engine and have a respected pilot be a spotter for you. Go back out and make your flight.
If at any time something is not right, call it quits for the day, even if it is only to change a glow plug. The key is to not have any worries about how the engine and airframe will perform.
Read and listen to the advice in the other posts in this thread.
GOOD LUCK on your day tomorrow
PS.... I hate you 'cause you get to fly tomorrow and I get to scoop snow
