Is the Zettelkasten just for organised people?

I find it very tiring haha. As I said in another comment, processing a single chapter can take me a full day or two. However, I keep reminding myself that I would rather spend a day processing a chapter well, and have literature notes to serve me a lifetime (potentially, at least), rather than reading a chapter in two hours and not remember a single thing the next day. When I REALLY need a reminder of this, I just look at my "Backlog" folder which contains old "notes" that are now pretty much useless: I didn't use a reference manager consistently during my first two years of PhD so there are a lot of citations which are unreliable; I didn't really summarise texts, I only read them and highlighted; I didn't use the cloud for a long time, so I lost a lot of notes; and I didn't have Obsidian, so a lot of my notes are just contained within the context of the place I read them, rather than being connected. Seeing three years worth of useless materials, and knowing that I read a couple hundred of articles/chapters but I have nothing to show for it, that makes me more patient when writing my literature notes now. However I also find it very exciting that I can future-proof some of my notes. I feel like I'm working for my future self.
