I'm going to pat myself on the back a little, and then chew myself out a little.
I'm tilting today. After running pretty hot for a nice long stretch, I got hit with a couple of coolers and missed several draws that I'd chosen to play aggressively, so I'm down 4bi's today. The 4bi loss, though, wasn't produced by tilt - I reviewed the sessions, and other than a couple of "normal" mistakes, I can see that I played my A (well, at least B+) game through that point - the tilt started after that and lasted for a single session (around 450 hands).
The most common way in which I tilt (and the way I tilted in that session) is to start second guessing myself left and right, leading to a weirdly tight passive game in alot of spots, including too many light showdowns. It's a strange form of impatience - I'm not one of those guys who goes aggrotard when I tilt, I just find myself thinking that Villain COULD have such and such busted draw/medium strength hand, and it's been a while since I've been involved in a 20bb pot, so...
OK, so great, I recognized my tilt and stopped playing. Yay! I'll take a break for a while and do something else after I post this. That's the pat on the back.
So here's the part that's not so great - I still haven't watched Tommy Angelo or any of the other "poker mindset" vids (Tolerance, Pokersense, etc.). I've read The Poker Mindset by Taylor and Hilger about 10 times and really liked it, it had a big impact on my thinking, but I can't compare it to Eightfold Path simply because I've never watched it, and I haven't worked on my mindset beyond that book in a very long time.
Keep meaning to get to it, time to kick myself in the ass and get it done.
