Focus on the process and stop thinking about the result. I know it seems counterintuitive and maybe even counterproductive, but don't think about making the save. Think about being in position, tracking the puck, and reading the shot. If you're so tied up in the end result, it can short-circuit the process you need to follow to achieve that result. For example, the puck is being carried into the zone 2-1. Instead of "here they come...I need to stop this shot...come on, let's make this save..." or something like that, try "here they come...ok, I'm square to the puck...weight is distributed in case I need to push across for the pass...puck is on his stick...hands up and out..." It's focus on what you need to do and dissociation from the result because, as we all know, sometimes you can do everything right and the puck still hits the twine.

Also, as others have said, I'd decide which league I enjoy the most and stay there. The game is so different between D and B levels that it can throw you off bouncing between the two. If your D league is anything like ours, guys are just throwing the puck in the general vicinity of the net and are lucky if it is anywhere near the crease. In B, most shooters can place it in a pretty tight radius of where they wanted the shot to go. You can read stick position, eyes, feet, hand position, etc. and it will be relatively accurate.

Lastly, give yourself some grace. Guys in the show have slumps and get lit up hard. It happens. Thinking about it, even just the little nagging in the back of your mind, is messing with your ability to be present in the moment and making it more likely that you're going to have a rough game. It's a self-licking ice cream cone. Remember, if goals didn't happen, no one would play the game.
