I listened to Building a Second Brain last week, and it helped me organize my folder structure in Notes. The main thing was making folders for active projects that I’m currently working on. After making that folder, it was easy for me to put all the loose files and notes into their specific folder. Now, they’re all easy to find. When I’m done with that project, I can move it into Archive. This is all built using the PARA Method from Tiago Forte. PARA stands for projects, areas, resources, archive. Make those four folders anywhere you keep digital stuff, then make folders inside of those for each thing in your life.
