Have you seen the post on the Games site called I Only Got 306 Fewer Reps Than Talayna? It's a really nice reminder that, in the grand scheme of things, no one judges us as harshly as we judge ourselves.
CrossFit is about finding your personal limits and pushing to be a little bit better each day. But you can't have a PR/PB without knowing your old score - the one your younger self delivered.
If you don't record your workout scores, times, weights, the only comparison point you have are the people around you. But they don't have your bone structure, your body composition, your emotional baggage, etc. and all of those things can influence what you can do in a given day. And you don't have their genetics or experience on a semi- professional jump rope squad.
You will be better at some things than you are at others, but the only person you need to be worried about beating is the you that did this workout a few weeks ago. And if you haven't done it yet, give it all you've got - don't go easy on future-you. Do your best. Write it down. Smash it later. Repeat.
Then high five everyone, including the EASY button, whenever you hit a personal best.
