Obsidian gives you total control over your folder structure, which sounds great until you realize that total control means total responsibility. I had a system at one point - actually, I had several. Each one made sense at the time when I built it, and each one stopped doing its thing when my notes started piling up faster than I could sort them.

I'd open the app, drop something in, tell myself I'd file it later, and then spend the next session doing nothing but dragging notes into folders instead of actually using them. If you’re a scatterbrain like me, you know exactly what I mean.
