My emotional state and mood at any given moment is directly correlated with how much I've learned and synthesized recently.

If there is a chapter I haven't finished reading yet or a half-formed thought I haven't yet drafted down in my own words, I am irritable and impatient and can't properly fulfill (that is, with a smile) my other responsibilities as a friend, spouse or household-maintainer.

As soon as I satisfy that intellectual urge, I'm super pleasant and happy to meet my other responsibilities.

I can't tell yet if this is a superpower or a crippling handicap. Or maybe these are always the same thing, depending on your perspective?

(This note was one of those instances)
