I used to enjoy making categories for things. Now, I think it's a waste of time. It's hard to predict how the categories will change, and it's annoying to keep up with the changes. I believe a more effective way is to dump everything in one place and make connections through tags, implicit or explicit.
Wanting to make everything neat and orderly, especially when it comes to organizing files on a computer, probably stems from the fact that file systems are like trees.
I'd like to explore how tree-less file systems can stop limiting us from thinking in terms of folders and subfolders.
Looks like I'm not the only one who has thought about this: https://fsgeek.ca/2019/05/09/graph-file-systems/
