(I am not to be self-promotiony or anything... the conservation of attention, time and _things_ are just topics that I spend a lot of time thinking and writing about. I am not trying to sell a book or anything. I don't even have ads on my site. Just trying to be helpful)
I do the same for photos. Really nice photos, I keep, and so I've got a nicely curated set of pictures from the last several years. Maybe a couple hundred. Thousands more, taken, gone!
Everything passes, of course. I just make it a little more intentional.
There's a joy in freeing myself from ever having to think about that stuff again, too. There's absolutely no cognitive burden, no cloud password to remember, no junk cropping up from time to time, none of it, because the stuff's just gone.
I've gotten old family photos handed to me from time to time, like from generations ago. I didn't know these people, didn't know anyone who knew them. It was just stuff. They could've been anyone. Why keep that stuff? Why make someone else haul it around? No one's going to care, and when I realized that, I stopped caring about most of it, too.
Example: I want to do a lot of sport in my spare time, so I can only play a little music and read almost no books. I'm fine with that.
Then I check which emotions come up when doing or not doing something, or when consuming media and information. I think about what those emotions do for me, if they help me on the way I chose to go or not.
Example: Somedays getting up and reading the news or HN makes me a bit miserable, so I close the tab and look at the table doing nothing instead to get back in my good mood.
I try to counter and unlearn emotions which I don't consider useful, and reinforce others. That works best by forming routines.
Those routines need to updated, some more often, some not. There is no formula that fits everyone.
Break down projects into buckets of tasks and make sure that each task item has sharp edges, then regularly review and put enough effort into it that you can start trusting yourself or your team to do this diligently. So that you can focus on the inevitable portions of your work that doesn't fit neatly into boxes.
But I am not entirely sure if that's really what you're asking ? Are you referring to the organization of reference information ?
