Zettelkasten

The Zettelkasten note-taking system is a system in which each note contains an atomic piece of information. Notes are linked to each other to form a highly interconnected graph of knowledge, which can be traversed to create new ideas, which otherwise wouldn’t have come to mind.

I use org-roam for my Zettelkasten, however there’s other tools that do the same or a similar job as well.
