"are you ADD/ADHD and, if so, have you been taking any recent meds?"
Don't think so. I'm not on any medication.
"If not, let's talk about your diet: tons of carbs but lack of protein? "
I guess so, but I don't feel that my diet is particularly unhealthy. So far today I had: an apple, oatmeal, avocado, carrots, some (whole-wheat) toast, a hard-boiled egg, a sweet potato, and a bag of steamed mixed vegetables w/ corn, asparagus, green beans etc, and just water to drink.
"How about sleep - getting enough of it?"
I usually get 6 – 8 hours (except at the beginning of the week when I'm typically feeling apathetic about school and stay up late working on a project or something), so yes, I think so.
"Sometimes burnout is the term for this whereas other times it is simple procrastination. So which is it?"
I prefer the same but it's a pain to line it up manually like this. I usually settle for vim's = operator, but that has the frustrating behavior of using as many tabs as possible (according to your tabstop) until using a few spaces. I can't find any way to change this; anyone know of a vim plugin to circumvent it?
PDF (technically Quartz PDF) is the native format for OS X, so that may be part of the reason why it seems like their text rendering attempts to mimic print like this.
