One problem I have is that I tend to write off low-grade stuff (migraine-related, fibromyalgia-related, or random) as ... well, unimportant, or "it shouldn't be enough to slow me down this much", or "maybe it'll just go away soon", and fail to consider that it might be something I'd be better off doing something about (taking something for it, giving up and going to bed, taking a hot shower, etc.) Until it's messed up my day -- or my week -- long enough for me to be frustrated at how much it has slowed me down, and finally realize that it's something I should've treated much, much earlier.
