I'm currently trying out vimwiki. Let's see how that goes.
Over the years I've tried so many tools, languages, workflows, and the only ones that stuck were the ones that were boring but timeless. I've not just been gravitating toward OrgMode for all my note keeping, but I've also gotten more and more into bash for much of my stuff.
There are downsides to that, of course. It's frustrating that I'm mostly limited to text-only things, for example. But it feels like any investment into bash/emacs+orgmode/emacs+tramp/emacs+? offers so much more than becoming reliant on app number <x> that quite possibly disappears or stagnates.
Why do you say you're limited to text-only things? Org supports links, images, code blocks, spreadsheet-like tables and such. For me the experience of migrating to Emacs+Org was more of a liberating type.
* To make sure that it actually is correct. Multiple times I discovered when reading the documentation that I only had guessed it sort of right and that there were some key bits of info that I had missed.
* To make sure that it is complete and that it gives just enough background information for those who want to use it without being in the exact situation that I was in. I.e. for myself in a couple of weeks/months.
There are more benefits. Like being able to structure it exactly the way you like it with links, tags, search, etc. And that you can show it casually to potential employers, who won't read a letter of it, but they can see that you actually put in work and understand some topics. This last point can also work for friends and colleagues.
In a quest to find ways to manage my focus, I've also taken up doodling. It's proven to be a good way to help keep me from falling down internet rabbit holes nearly as badly as I used to.
