This sounds a lot like me! Though I’m closer to 8 or 9 inked at a time. Lots of notes in meetings; I have a few stub nibs inked up that I use for headers, then rotate (less systematically) through the other pens throughout the day. The changing colors for each meeting help to provide a good visual separation between meetings in my notes. Plus, it’s a nice little change of pace to “reset” between meetings by choosing a new pen.
