My main issue with taking/making notes is that now I must worry how to store and organize them. Back in college I'd take them in a notebook, review them for exams, and then get rid of them by the end of the semester. I've tried blogs (static site hosted on gitlab), markdown files with Vimwiki, Obsidian, and now I'm using Notion. The common thread among all of them is worrying about how to organize them (e.g., file structure, tags, by topic, etc).
