Yes indeed, anytime anything is worth remembering (or connecting with other notes) I write it down. It interrupts reading, so I don’t churn through as many books.
I used to set goals like x books per year, but now I realize it’s a vanity metric and instead read for insights.
I use Obsidian for note taking, which supports images too.
Pondering about trying out Zettelkasten, I'm thinking whether it would make sense to take notes in a sequential log ... like one file per day/week/month/year ... and then regularly, like daily or weekly sort things in to the zettelkasten structure.
Anybody tried that?
AFAIK, this is how many data(base)-systems do to make writing more efficient: Write down into a write-cache of some sort, and then do batch-wise indexing as a separate process.
