As an umpire myself, you will have the good with the bad. On every call you make, half the people in attendance will be happy and half will not. Except the obvious strikes, the corner calls are the same...half will be happy.
You can never make them all happy.
But if you can check your ego, learn and really know the rules and understand that your job is not to embarrass the coaches but to call the game as fairly and evenly as possible then you will love it.
It's the best view in the house!!
