On every whistle that isn't resulting in a faceoff in my end, I skate to the right (always the right) corner and just stare into the glass. I just want to clear my head and not focus on anything that has happened up to that point. I certainly don't want to watch the other team celebrate, or my team hang their heads or glare at me if it was one they *think* I should have had. It also doesn't let them see when I am burning holes through them with my stares after they do something glaringly wrong. You can't let the bad third goal, which was seemingly a big one in the game, affect your play later. It doesn't matter if it was your fault, their fault, no one's fault, just forget it and focus on making the next save. Always making the next save - as opposed to "not letting in any more goals". Late in close games, I will literally continually say to myself "stop every shot". Goalie is a much more mental position than skating out. Success is built from trying to ignore momentum, rather than harnessing it like a skater. Every shot is unrelated to the one before it, and the one after it. You need to have a short memory and the ability to ignore everything but the puck.
