I stopped using Obsidian, etc for this reason. I spent a fair amount time creating a database but never got real value out of it. It was just a waste of time. I'm questioning the whole premise of these systems. Why do I need a personal database when I can find anything I need on demand online?

I now have a few simple text files with project ideas, book notes, and todos. It feels much better and I don't spend time managing it.
