Editing footnotes is one of the things I always think I will enjoy because it requires relatively little brain power and I can do it to music without getting distracted. (This is relative - I'm not good at focusing under the best of circumstances, but let's be real, changing commas to periods is not quite the same as struggling to articulate a theory of human agency.)
And then I try to navigate the Chicago Manual of Style and try to format things with like thirty tabs open to help figure out how to format snarky asides made in footnotes or references to e-journals that refuse to do anything but look like a half-baked journal footnote or an overlooked hyperlink. And slowly, I lose the will to live. I've been working on this off and on all day and I'm about two hours away from replacing all of these references with one footnote that says, "I tried my hardest and concluded that if you have any questions it's probably best if you just call me."
