There were games that I had during my first year where, if it had been my first game, it would have been my last game. This is now my third year and I still have games that are not as much fun as others, but the overall experience is well worth it. I love the game of basketball and enjoy officiating.
So, you have a tough game or two...shrug...the good will far outweigh the bad.
You are not as good as you appear to be at your best and you are not as bad as you appear to be at your worst. Do the best job you can and have fun!
