First game tomorrow

Great advice has been given.
Here's a few more.....

Try to relax
Don't go looking for things to call
Don't call out of your primary area
Never blow your partner's lines
Make sure you point in right direction
Don't explain judgement calls
Stay with your partner between quarters
Never disrespect your partner
Give the perception that you care
Use the T as a tool (not a weapon)
Think of the players/coaches as your customer
Check your ego (and problems) at the door
Keep your mouth shut unless you can improve the silence!
Always continue to learn and improve.
