Thinking more about feelings of finiteness and productivity and disappointment

I think maybe more than to-do lists sometimes what I need is a did-do list, like writing out everything I ended up doing because sometimes it's a lot and then because trauma/brainweirdness/other sources of memory problems I just

don't know I did it

So for example I was down in the frumps about how little I got done this weekend and, like, I thought about it hard and realized "wait a second, yesterday I powered through the entire intro to logic and computability textbook that other lecturers use at [community college] and took a bunch of notes, wrote down a sketch of how one could low-key introduce some category theory to smooth out the connections between topics, and found a fun paper on the categorical semantics of hoare logic" and then I was like "wait, this morning I literally spent several hours on a talk I'm giving next week"

and, dear reader, when I made that post about how frustrated I was I'd literally forgotten that these things had happened

this problem affects more than just my morale, too, because I've definitely had times where I rediscover some big body of work I'd actually just memory-holed that I'd done

so, yeah, maybe I need to make a habit of writing down what I did each day before I got to bed and actually reading it the next morning before I do anything else

@left_adjoint I have begun to enable the "Daily Notes" plugin in my personal Obsidian notes and do what I used to do at my old job and keep a rough log of things I've done.
@left_adjoint Totally identify! I keep a "calendar" spreadsheet in the cloud, where every night before I suspend the computer I note where my day went. Physical work I can usually remember, but brain work I rely on NirSoft BrowsingHistoryView which combines the history from all browsers and many other apps. With those hints I can bring back the feeling I actually accomplished something today!
@left_adjoint If you use to-do list software, you can usually set it up so it adds the done tasks to a file - if worse comes to worst, through IFTTT and Google Docs. I had that for a while, then switched to a paper journal, so that if I forget I can look it up. And I do forget!
