I have a few tidbits:
Listen to your coach not a bunch of keyboard warriors.
Be careful of the adrenaline dump. Keep a level head.
It's easy to get tunnel vision, keep your eyes and ears open.
Do what you do. In any sport, do what you do best and don't try to beat someone at their game. If you wrestle, wrestle.
And the piano, it sounds like a carnival
And the microphone smells like a beer
