(General content note: A lot of my thinking has really changed since the old days of this blog. There’s some weird, mean, and polemic stuff in there.)

Cal Newport makes the distinction between work that you can handle with a GTD system vs “deep work.”
I would call these buckets “legible work” vs “illegible” (or “not-yet-legible,” or “right-at-the-bleeding-receding-edge-of-legible work”).
It would be nice if there were a single lens to “register” all work/life/stuff, but it doesn’t seem like anyone’s found a way to do it, so far.
I try to use the minimum number of tracking systems that, on balance, leverage my quality of life. I have a GTD-esque system in google spreadsheets for work. I have a low-level tactical system using index cards for all short-range life stuff. I still don’t have a medium and long-range systems that fit my brain and life-situation, though not for lack of lots of careful experimentation over many years. Working on it.
