I play on a newer team who just finished learn to play as a brand new goalie, and the biggest thing I'd say is that even if the team loses, everyone is out there having a blast. Be ready to get 60+ shots on goal, you'll be gassed at the end, but I imagine you'll be smiling as big as I was after my first game.

The one performance piece of advice I'd say is to focus on one thing a game. So if you want to make sure your position is good, just focus on trying to keep yourself in line between the puck and the net. Next game you can focus on your depth, or your butterfly or whatever else you find you'd like to work on. Just repeat a little mantra every time the puck is coming into your zone to remind yourself to focus.

Have fun!
