I used to imagine I can have a system that would keep concepts together and continuously reorganize them manually as the goal is to both not keep it in the head, but also know what's there. However, as the time passes, the cognitive load of reworking it increases dramatically, and the use and the ability to find stuff in it drops as contexts mutate through that rearrangement. It is very difficult to manage change in that kind of system no matter if it's low-tech or high-tech. After some mismanagement you just lose trust in it and drop for a new one.
About a year and a half ago I started a lowtech weekly diary approach.
Documents folder on your computer or a GDrive/Dropbox/whatever.
Folder for the year, and then folder for each week of the year. Usually create it on monday and transfer what I expect to need that week. Treat that folder as my desktop for that week and move on the next week. I now have a year and a half of such notes, am confident I can find stuff and when I open such snapshot I'm quickly able to gather all the needed contexts that were relevant then.
I think you would be very interested in Roam Research if you’re ever looking for a high tech solution again. Only recently entered public beta, but it seems to by nature organize notes very easily and fluidly.
