There's something weird about how my mind works. The latest example was with this article. The first time I tried reading it, my eyes sort of glided off the page and I couldn't understand anything. I waited a day, without thinking about the article at all, then tried reading it again. And suddenly everything was completely obvious and I couldn't see any difficulty. The same thing happens with math problems (when I was a kid I would often wake up with a solution to some problem I heard the day before), complicated programming tasks, etc. Any ideas why this happens?
I'm not sure why it happens, but my impression is that it's not unusual.
If it's worth saying, but not worth its own post, even in Discussion, it goes here.
