Whether you just refer to them, or you continuously edit them. Asking because it's always fun to hear about other peoples' use cases and experiences with Obsidian. And because I was thinking about some reference notes I made that I do not actually use for one reason or another, but it boils down to something like this: https://xkcd.com/1205/. I miscalculated how much pain or time making the reference resource would save me. That note gets 0 visits. Meanwhile, other notes I made get near-daily references, and I feel so glad that I made that note because it makes my life a little easier or better.
I have what I call an “Ivy Lee” note that opens in its own window at a particular location on my second monitor every time I open Obsidian. It contains a list of things that I “must do” that day, a second set of bullets for “stretch goals” for the day and some “no need to worry about” entries in case I get anxiety about those things. I edit it the previous evening. Part of the Ivy Lee methodology I’ve been following for quite a while now.
