I’m pretty averse to talking about notetaking, research, keeping a zettelkasten, and other “self-development” topics, because I feel like this sort of metacommentary (metablogging? metawriting?) feeds into itself, and sends me, the creator, down a trail toward producing more content like that. I have benefited from how-to-write content, to be clear (and how-to-zettelkasten, most recently). But I’m not trying to be a teacher around writing (or related subjects) because there are other subjects that interest me more, and as long as I am not locked in financially to producing one kind of material, I owe it to myself (and potential readers) to be more discriminating.
That said, if you ask me, I would be happy to point you toward resources that have helped me. Maybe I’ll even put a page together listing some of my favorite YouTube channels, websites, and the like to learn how to do things like writing, Zettelkasten, whatever.
If I do make how-to content in this vein, it would probably be in video.
