I use the common folder-of-text-files method (currently with Ulysses, although I've used other apps in the past). Any time I need to write something down, that's where I go first, unless I'm drafting a document that needs to be sent to someone else.
Here is when it gets used most:
- Researching something online
- Preparing for a call or meeting
- Taking notes on a call or meeting
- Random ideas I want to save
- Important information I want to keep (but not so secret that it needs to go in a password manager)
- Outlines of documents I want to write
- Snippets of code I want to save
I think the key for most of these, particularly BATF/BASS is the "always open" part. I've recently started playing around with Obsidian mentioned elsewhere and if you don't have it open at startup it's easy to forget about it. And you need to be pretty diligent at the beginning of adding interesting/educational things to your documents while you're still trying to form the habit.
Having a decent organization system is pretty important too (one of the main failings of BATF/BASS in my experience). If I need to scroll through a bunch of development and business stuff to find that interesting physics article that is suddenly relevant again I'm much less likely to do it than if I have a "physics" document or folder I can see and get to easily.
And I agree with pc86's thoughts on 'decent organization system' and "always open". I am working on getting better at it with pen/paper.
I have a couple of macros set up to put in the current date, and a different color for bullet points that are "done" or not completed yet
This is the only one that works for me, and I've tried Org-mode, evernote, onenote, joplin, notion, etc. It's a combination of no-friction to open (I literally just press alt+~) and opinionless. If I want to paste something in there, I don't have to fiddle with a UI to get it how I want, because the formatting doesn't matter at all.
