How do you organize your work or personal lives?

I am a sucker for productivity apps, for both my professional and personal lives. When I failed to find the perfect task tracker for my needs, I created my own - Finale To Do. https://www.producthunt.com/prod... You can check it out above, but I would like to hear how others organize their time. To-do lists? Task managers? Notion templates? Pen-paper? Pure brainwaves? Tell us how YOU do it!
