Self-cataloging can be become a method of procrastination. But that doesn't mean that there is no value to be found in methods like Zettelkasten. The activity of looking through your own Zettelkasten has the potential of creating associations and sparking ideas. That can be very valuable and requires some care of your notes. But trying to find the perfect taxonomy for your own notes is foolish mistake. The technical limitations of the original Zettelkasten, makes refactoring the notes to the current approximation of the perfect taxonomy such a huge task, that it is usually avoided.

A nice example of a limitation that supports creativity.
