Avoid sarcasm. Don't insist on the last word.

Hear only the things you should hear - be deaf to others.

Keep all your personalities out of your work. Forget and forgive.

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.

I'd hate this to get out but I really like opera.

Keep your eye on the ball.

Never charge a player and, above all, no pointing your finger or yelling.

Review your work. You will find, if you are honest, that 90% of the trouble is traceable to loafing.
