I've felt like I'm too aggressive early in sessions for sometime now. Your article prompted me to act.
As I was taking my seat in a 3/5 game, with a $300 capped buy-in, a 40 something Asian lady was raking in a pot and had AA flipped open in front of her. The board only had 3 cards, and the player to my right commented how he would not continue against her if he couldn't beat AA, and they were both having a little laugh over his comment. Next hand, first hand for me, I'm dealt QQ in MP and open for 4x. It folds around to the Asian lady in the SB and she makes it 12x. Normally, I would look at a flop, but based on what I'd heard of the previous conversation, and my decision to avoid tough spots early in sessions, I laid it down.
