Signs of Burn Out?

[Umpteenth]

Am I burned out on officiating? This is my 11th year.

I don't have fun calling games any more. I actually dread seeing the email telling me I have new games. I find I have very little tolerance for coaches asking simple questions about rules that they really ought to know. Fortunately, I haven't verbally lashed out at any of them like I want to sometimes.

I've never been in this for the money; I've called because I enjoyed doing so. But, if that level of enjoyment isn't there, should I walk away?

Am I doing a dis-service to those involved if I show up to a game with this attitude?

I guess if I'm asking these questions, the answer should be obvious to me. I probably shouldn't be working games right now.

What are your signs of burn out?
