For me. Journals are a big thing. In particular, I keep a daily log of work I completed each day, Basically a List of years > month > and date (using the nice date format). Then a list of the different projects I’ve worked on through the day, if multiples usually proceeded by their own hash tag.
I will also keep an individual project document for each project with the details of it, be it specifications or account credentials or references to API etc depending on the various projects.
I keep a similar list for a daily journal in my personal life as well, or to track something I need to daily (though can’t get into details on it).
