Hustle, Hustle, Hustle when you are on the court.

Good Posture at all times when you are on the court.

Strong, crisp mechanics. Strong voice.

Listen to observers. Don't debate with them. You are not always going to agree with an observer's opinion, but arguing with them will not serve you well. At the most if you don't agree you may ask a question like "What do you think I should have done differently on that play?, listen to the answer, and move on.

Don't be afraid questions but don't ask a million questions.

When not working a game watch another game and listen to the observer's comments but don't interject yourself into that game.

Don't point out other referees' mistakes to observers.

Off-court wardrobe: Khaki-type shorts with golf/polo type shirts; or nice, matching sweat-suits.

Those are some of the things you can control.
