The objective of a referee is not to get mentioned. I tell a lot of young referees that not being mentioned is king. If you can achieve that, that then it has been a pretty good game.

If at first you don't succeed, get a bigger hammer.

The scrum and the tackle are the two really contentious areas of the game. If you get those two aspects right, most rugby matches will work in your favour.
