How do you handle confusion when reading for a Zettelkasten?
When reading texts, I occasionally find that I didn't understand something very well.
However, when there are gaps, I'm not too keen on the idea of referring to resources until I can fill in the gaps. It means that I have to switch from writing to reading. Reading is low effort to me while writing is demanding. I'm most energetic in the morning. Thus, I'd rather use my mornings to write than to read if I have anything to write about.
But, if I split the tasks, I need to do something about what I've written so I can address the gaps and re-use the text. I've tried multiple approaches to deal with this to no avail.
So I ask: What is your approach to handle gaps in your understanding when processing reading notes?
