Keep all your personalities out of your work. Forget and forgive.
Avoid sarcasm. Don't insist on the last word.
I'd hate this to get out but I really like opera.
Keep your eye on the ball.
Review your work. You will find, if you are honest, that 90% of the trouble is traceable to loafing.
Take pride in your work at all times. Remember, respect for an umpire is created off the field as well as on.
Keep your temper. A decision made in anger is never sound.
