Similarly, I only qualified at 53 and remember my first two games vividly - quite similar to yours, really. U13 girl's game as they transitioned from 9s to 11s, so it was more about encouraging them and talking throughout the game; 2nd game was an older boys' game and a national cup quarter-final, though I didn't find that out until just after kick-off. Unnerved me a little as I started thinking about the procedure for penalties when I should have been focused on the game in front of me
I concur with much of what has been said:
- with experience (and I'm still trying to gain some), being confident even when inwardly unsure carries loads of weight. When I watch refs now, this is so evident - whistle, point and move away from the area. If you are unsure, the actions of the players can often tell you which way a decision should go;
- you don't 'give' cards out. The players ask for/earn/demand them for their part. My second game involved a few yellows and a red, that was the uncertainty gone after that;
- booking an individual for the team's cumulative misdemeanours can settle things down, including for dissent;
- I use the captains to relay my message to their players, I find a word in the ear can then quell some rising tensions;
- once I reflect on a game, I score myself on various aspects and keep a track. It's subjective, but it helps me think about aspects where I recognise I've not been as good as I could be;
- when the ball goes up in the air, it always comes back down so you don't need to follow the flight, use the time to scan around you for the positions of the players.
Nothing revolutionary there, just things that come steadily with the minutes.
