Less Is More?

What has worked for you in terms of organizing the many layers of this thing? I find myself once again over categorizing and sub categorizing everything. I have tried every paper planner, app planner, web based planner, etsy templates, spreadsheet under the sun but I still can’t find a system that works. I’m liking notion but I feel I’m doing what I always do.. over do, over explain and overwhelm. But my life has so many different aspects to it. Is there a rule of thumb for this? How do you break your life down into drop down menus? For context I have 2 careers, 2 kids, I’m the family secretary and task manager as well as the appointment maker and calendar keeper. I’m trying to get organized in a number of different ways from listing out all paid subscriptions to organizing my computer files, organizing kid clothes and cleaning up the apps in my phone. I have my hands in a number of entrepreneurial endeavors at any given time as well as the many charitable organizations i partner with. To add to this my brain constantly is quickfiring projects, poetry, and business ideas at me. How does one use notion to keep all of this madness organized without the overwhelm? Oh did I mention I have adhd lololol ????
