One or two pots over the evening all the difference?

This is actually a take off of a thread TP has going in the Bad Beat forum, but I honestly wanted to post about this before and he just reminded me with his story.

Do you find that 1 or 2 pots over a session make you a winner or loser for the session? Last trip to Atlantic City sticks out in my mind, at a 5/10 limit game I get AA and raise pre-flop with a total of 4 callers including both blinds do 50 in the pot pre flop, flop K-7-2 rainbow which is just what I wanted becsuse the guy with the K in his hand is gonna play till the bitter end unless an Ace fall, and I doubt he has K7 or K2, so I bet after the flop and only he calls both blinds fold, 60 in the pot at this point, turn is 8, I bet he calls, river J, I bet he calls so $100 in the pot and he turns over KJ for two pair. I ended the 9 hour session down $60, so the pot would have made me a winner, though not a big one, but still it was the swing hand for me I think. I this pretty common for everyone or am I just looking too much into it?
