The framing of "permanent notes" or "evergreen notes" has probably hurt a large portion of the personal knowledge management space. Too many people are approaching these as some sort of gold standard without understanding their goal or purpose. Why are you writing such permanent/evergreen notes? Unless you have an active goal to reuse a particular note for a specific purpose, you're probably wasting your time. The work you put into the permanent note is to solidify an idea which you firmly intend to reuse again in one or more contexts. The whole point of "evergreen" as an idea is that it can actively be reused multiple times in multiple places. If you've spent time refining it to the nth degree and writing it well, then you had better be doing so to reuse it.
Of course many writers will end up (or should end up) properly contextualizing individual ideas and example directly into their finished writing. As a result, one's notes can certainly be rough and ready and don't need to be highly polished because the raw idea will be encapsulated somewhere else and then refined and rewritten directly into that context.
Certainly there's some benefit for refining and shaping ideas down to individual atomic cores so that they might be used and reused in combination with other ideas, but I get the impression that some think that their notes need to be highly polished gems. Even worse, they feel that every note should be this way. This is a dreadful perspective.
For context I may make 40 - 60 highlights and annotations on an average day of reading. Of these, I'll review most and refine or combine a few into better rougher shape. Of this group maybe 3 - 6 will be interesting enough to turn into permanent/evergreen notes of some sort that might be reused. And even at this probably only one is interesting enough to be placed permanently into my zettelkasten. This one will likely be an aggregation of many smaller ideas combined with other pre-existing ideas in my collection; my goal is to have the most interesting and unique of my own ideas in my permanent collection. The other 2 or 3 may still be useful later when I get to the creation/writing stage when I'll primarily focus on my own ideas, but I'll use those other rougher notes and the writing in them to help frame and recontextualize the bigger ideas so that the reader will be in a better place to understand my idea, where it comes from, and why it might be something they should find interesting.
Thus some of my notes made while learning can be reused in my own ultimate work to help others learn and understand my more permanent/evergreen notes.
If you think that every note you're making should be highly polished, refined, and heavily linked, then you're definitely doing this wrong. Hopefully a few days of attempting this will disabuse you of the notion and you'll slow down to figure out what's really worth keeping and maintaining. You can always refer back to rough notes if you need to later, but polishing turds is often thankless work. Sadly too many misread or misunderstand articles and books on the general theory of note taking and overshoot the mark thinking that the theory needs to be applied to every note. It does not.
If you find that you're tiring of making notes and not getting anything out of the process, it's almost an assured sign that you're doing something wrong. Are you collecting thousands of ideas (bookmarking behavior) and not doing anything with them? Are you refining and linking low level ideas of easy understanding and little value? Take a step back and focus on the important and the new. What are you trying to do? What are you trying to create?
