Bad Game

[Grail]

Worked a game on Monday that was perhaps the worst game I'd ever done. From the first whistle I felt like I had forgotten everything I'd ever learned about being a ref. Tried to focus on mechanics and just seeing the game, but I was still horrible.

The question is how do others deal with this? I tried everything during the game, but to no avail. The good news is I had another game Tuesday night and had no problems. I felt like I was a completely different (and actually decent) ref.
