Okay, this is a bit of a weird problem.

I play significantly worse when I am doing well. I play my best game when I am down a significant amount of money. This is probably just because I play tighter when I'm down I suppose. But it's still weird. Anyone else have this problem? Any suggestions on keeping focused when I am up? Right now I leave a table when I am +5 BB or more and sit down again with my initial buyin. I managed to be up 25 BBs last night over 4 hours using this strategy. Still, seems a little silly.

Meditation maybe?
