Should I have just stopped playing after the QQ hand below? I'm starting to think so. Am going to work on a post about the mental aspects of this game. Any references/links/reads you all can suggest is greatly appreciated.
As for now, I'm going to looking over my HH and studying exactly what went wrong tonight.
Thanks for your help,
UPDATE: After taking a break and then reviewing my HH (was playing way too loose from early position and way too passive from late position), I sat back down for an hour before bed. Won 2.5 buy-ins in 30 minutes and shut 'er down for the night. Net loss for the day: $0.30.
