I haven't looked at mine once, actually. I will obsess over it to the point where I'll dream about it otherwise and that's not going to make me feel any better about this process. I have it and all its permutations memorized and occasionally a sentence that I wrote pops into my head and I cringe, wondering what I was thinking. I've also thought of all sorts of things I wish I'd said.
My main fear is that I unknowingly put in the secret phrase, whatever it is, that makes all adcoms immediately reject me.
