Never charge a player and, above all, no pointing your finger or yelling.
Hear only the things you should hear - be deaf to others.
Review your work. You will find, if you are honest, that 90% of the trouble is traceable to loafing.
Keep your temper. A decision made in anger is never sound.
Take pride in your work at all times. Remember, respect for an umpire is created off the field as well as on.
Keep all your personalities out of your work. Forget and forgive.
I'd hate this to get out but I really like opera.
Keep your eye on the ball.
Avoid sarcasm. Don't insist on the last word.
