In the age of mass information and the knowledge economy, it's become necessary to manage (classify, store, index, retrieve, etc.) the mass of information. Personal knowledge management is the given term. This term is relatively new and some think unnecessary but it's popular on the internet. ("Personal information management" is the older, perhaps outdated term.) There exists various approaches, both analog and digital, to systemize personal knowledge management. The [[Zettelkasten]] method is a well known one. If you dig around online enough, you'll eventually run across Andy Matuschak's "[Evergreen notes](https://notes.andymatuschak.org/z4SDCZQeRo4xFEQ8H4qrSqd68ucpgE6LU155C)." Basically, he says notes should constantly be updated, be atomic (short, single topic), & linked to other notes. He claims this works better with how humans think & is more effective at developing insight. This is a useful example to look at and many are familiar with it. His other article, "[Why books don't work](https://andymatuschak.org/books/)" is also great to read and goes further into the idea of organizing our information to serve the way we actually think.
