Ok so I've broken my rule on game selection. Full ring has become so increasingly boring over the last month that I just can't stand it any longer. It's very easy to just pitch a tent, set up camp and wait for the nuts. While I understand this a very profitable way to beat 2NL, it's just not going to do it for me. Auto-piloting my way through 2NL is counter-productive and goes against every rule I've set for myself in the op. I'm not completely giving up on FR but I'll be playing a lot more 6max going forward. I look forward to playing more hands against players worse than me and hopefully getting in to a lot more interesting situations, which will be much more +EV in the long run.

Also, I've finished reading Harrington on Online Cash Games. It was a pretty good book and there's parts I plan to go back and read again. But for now, I've moved on to reading a book called The Poker Mindset. It's a very calming piece of literature and from what I've read so far, I definitely recommend it to anyone with even the smallest of tilt issues.
