I'm one of those people who went pretty hard into the whole "Second Brain" movement (using Apple Notes first, then Obsidian).
~6000 notes later and I've started finding the whole thing overwhelming and pointless at the same time. The vast majority of notes I have don't need to be noted down. At most they could have been a journal entry rather than a separate, curated piece.
Usually I hear something like "excessive noting means you're less likely to try to commit something to memory because you know it's there when you need it". (This is touted as an advantage of the Second Brain concept, incidentally.)
But I've actually found something different as well: excessive noting means you're actively engaging with significantly more information, and most of it is designed to be (or at least should be considered) ephemeral. Noting so much of it down is effectively the digital equivalent of hoarding junk, and the mental/memory repercussions are similar to the physical repercussions of hoarding actual junk.
I save working knowledge elsewhere as Topic.md in subfolders so I can remember how I deployed an app or fixed a recurring issue etc.
(If this is a joke, well, I salute your dry humor.)
Although I definitely should take more, because I can never remember what I've done when it's performance review season.
