Nice, I liked it a lot! Everything you wrote is 100% correct, both in real life and in the sport.
It reminded me of a short story too:
In my first comp I dropped the stone behind me and felt like such a huge asshole, but thought "shit I've only got 15 seconds on the clock." so I said to myself, "fuck it, gotta try and get it anyway." I got the stone up to my thighs but the timer expired so the rep didn't count. The point is, you can spend the time complaining or just roll with the punches and do your best.
