Besides what the other guys already said, there's one more important one. DON'T badmouth your competition. It will hurt you more than them.
When all else fails, vote from the rooftops!
If you don't love it, leave it:
Let this song I'm singin' be a warnin'.
If you're runnin' down my country, man,
You're walkin' on the fightin' side of me.
God Bless Our Troops!
