Long session

I just had a super long session, playing 2800 hands. I started out playing some 2/4NL and some 1/2NL heads up. It was just one of those days where nothing went right. My lowest point was -$2832 (I think this was when I opened up a table at 3/6). I know it's very superstitious, but whenever i run bad at lower limits, i run awesome at the higher levels. Also, it just so happens there was an extremely bad player at the higher stakes. i checked my pokertracker stats and it says that i took him for $2.4k. So that upswing at the end there was pretty much all him.After playing a session at 1000NL, I realized that i am not ready for that level. I'm not nearly aggressive enough for those games.
