I did some work today, surprisingly enough. I also found an error in the paper I'm transcribing. It's an "off-by-one" error, and it confused me for a long time... It may turn out that correcting this error would double the constant in the end, so I guess it's not a critical error. Still, it confused me.

I think I'm a vague perfectionist in terms of writing mathematical stuff. I always want to explain it in a way that is understandable upon the first reading. And that's why my progress has been very very slow...

I guess the break that I needed isn't going to come soon.
