I often hear the words, "I need to video my set, so I can see the all the things i screwed up." They're usually born of a genuine attempt at accountability -- a need to realize you're imperfect and be willing to improve, while studiously avoiding self-aggrandizement.
I'd like to suggest an alternative for watching your set: self-aggrandize. A lot.
Try to catch a good set. Play the best parts over and over. Relive the fun, the joy. Try to figure out all the things you did right, so you might have moments like those again.
Maybe it was a tag that should be a punchline, or new wording, or timing. Maybe it was an approach that allowed you the freedom and confidence to improvise.
Whatever it was, you have the Art Sturtevant Seal Of Approval® to relive it, learn from it, and enjoy it.
I'm not saying you shouldn't spot the occasional gaffe and file away a quick fix while you're watching your set. I'm just saying don't watch the set for the gaffes.
Watch it for the good stuff.
