This is my system for keeping on top of my to-do's, projects, and collections. The key is to have one main area or topic to focus on per day. So, for example on Mondays, I focus on working with my clients (I'm a freelancer) and planning out new work projects.
I call this personal productivity system "Areas of focus," and it's built entirely in Notion. In my case, it covers both my private and professional life, but it can easily be adapted for many other purposes.
