This is a most excellent reply. I am one of those players that used to agaonize and always second guess my decision to leave a game. This post explains the criteria for making that decision perfectly.

Just because you are up for the session does not mean you are playing well and just because you are down, does not mean you are playing poorly.

It is difficult for most people (myself included) to be honest about the quality of their play in any given session and the quality of their opponents play. If your opponents are playing poorly and you are playing well, you should stay regardless of results. But if your opponents are playing well and you are playing poorly, you should leave because eventually the better players get the chips.
