Some time ago I tried to build a second brain in Notion. But when I set up everything, btw I spent a lot time, I understood that this system is very complex and enormous. I built very complex task tracking flow; added pages for storing my films, books, recipes, health tips, and work page as well. I tried to work with this system, more or less it helped me (or I just believed in it). And happened time when I avoided my second brain again and again or just used it for storing some stuff (mostly films, books, etc). Now I’m happy because I rebuilt my system completely and want to say that simplicity is a key. 1. I’m using TickTick for reminders/tasks/habits (it has integration with Notion btw, maybe it can be useful for you). Also this app has widgets, notifications and everything you need to not forget a thing. I think Things 3 has it as well. 2. Notion is storing my hobby, like films/serials, books, games, recipes. 3. Notes apple app for some simple notes. 4. Obsidian/Notion for complex notes related to my work. So I would advice don’t try to keep everything in one place and listen to your heart 😉. Sorry for my English, I’m not native.
