γνῶθι σεαυτόν

[liminalia]

Good gods. Had a difficult night last night involving a recurring issue that has troubled me for months, spent a lot of time thinking about it late into the evening and this morning, and finally realized in the shower that the answer was so incredibly simple, and should have been blazingly obvious to me a long time ago, but I've wasted way too much time on blind alleys and irrelevant things.

What is it about the shower that seems to aid thinking?
