I just opened one of my 37 notebooks and out fell a pile of notebook cards welded together with mismatched post-it notes. That's a lot of notes. There were some recipes, some business to-dos that were never to-did, and sweet words I left my wife. That is to say, I don't have a solid notetaking system. Do you?
I'm A.D.D and I seriously get ideas while I'm half asleep and then get yelled at for grabbing my phone. Surprisingly I have a random system that works pretty good... I have keep notes for the oh I need to organize this later, I'm half asleep, or my wife might kill me if I don't put my phone down. I have multiple emails... So I use one for my lead magnets and one for my writings. Obsidian is a lifesaver. The amount of folders I have is embarrassing, but I also have to keep organized to keep up with my brain. My journal is randomly on penzu.. I have been using it for 10 years and keep adding to it because I'm too lazy to figure out a better place to put it. I'm sure you're sorry you asked lol
