[AndyS]

Try not to think about your beats and instead analyze every possible instance where you went wrong?

-involved in too many pots?
-being stubborn when you hit Q high flush with QQ?
-didn't give credit to the person calling your KK when an A hit the flop?
-3 betting pots with good hands from early position?

All of these and more can be costly mistakes and will tend to compound themselves. Think about ways you could have played differently or gotten out early and focus on analysis. I'm sure not every one of your beats was on the river. It's easy to get frustrated b/c remember that your big hands will lose big pots if you play agressively.

Rethink, Regroup and Rake those pots in when you get the best of it again
