Patrick, another great post as usual! I too have been using the Circa Junior for a few months, after having been attached to my letter-sized Circa for over a year. While the larger was easier to maintain, I found myself wasting a lot of paper. Often, I just didn't need the 8.5" x 11" size. My Circa (complete with a zip-folio) is organized as follows: 1) Notes: Blank paper to serve as an inbox and note-taking area. 2) Agenda: My calendar. I print blank weeks and months from Outlook and handwrite my appointments and commitments. It might seem like a bit of extra work, but I don't want to be computer dependent, or hand over my personal data to the corporate Exchange server. I keep two to three prior weeks before archiving in a separate notebook. 3) Lists: Everything from Actions, Waiting, Agendas, Someday/Maybes, Reading, etc. in this section. Each topic gets a separate page. I prefer handwritten lists, although lists for recurring tasks (ie. Weekly Review, morning/evening routines) are printouts. 4) Reference: Anything related to my current projects or things I refer to regularly to here. As part of my Weekly Review, I archive those pages that are no longer relevant. When it's time for a refill, I use 28-lb copier paper, cut into halves with a paper cutter. I find the 28-lb paper thick enough to absorb fountain pen ink without any bleeding and study enough for the Circa rings. I prefer blank, unruled pages as they allow me to be most creative. This system is working for me, but I'm always looking for ways to improve!
