Eye(Q)norite? (REAAALLY bad joke FTW) Drives me up the wall.
Since I fluctuate so much, I feel like I might be failing to pinpoint what's ACTUALLY keeping me from getting better because I'm always focusing on why I'm not doing well during those short "I can't cube for beans" periods. If I'm cubing for too long, sometimes those periods last much longer, and after a while, I'm just like "SCREW THIS CUBE!" and I quit on a bad note, just so I can calm down and start again the next day.
I remember a time at the MIT Spring comp 2010, when I was sitting by myself practicing before competition. Right then and there, I almost got my first sub-13 RA of 12 (or maybe I actually did, I can't remember). So I was really proud of myself. So then I met Anthony Brooks. He asked me what I was averaging. I said low-13s. I thought maybe I'd still be in my little "cubing high" when racing him.
Big mistake. I made myself look ABSOLUTELY RETARDED. Started getting 14s, 15s, and 16s right there on the spot. I'm sure he remembers that. If he's reading this, he's probably laughing... But then again, I'm laughing too. It was pretty funny. Potentially FML worthy.
