I'm leading a rationality training group. We're working through the most recent CFAR curriculum, but I also want to work from parts of the sequences.

Which posts in the sequences were particularly impactfull for you? Not just ones that you found interesting, but ideas that you actually implemented in your thinking about object-level stuff.

I'm particularly interested in posts that we could spin out into techniques to practice, like noticing confusion or leaving a line of retreat.
