I reserve a double page for every month that passes. The left page is a monthly calendar with days and weeks marked, as well as events. A Book Dart serves as a cursor for the date as well as a bookmark, leaving the Moleskine string free for other purposes. The right sheet is entitled with the month and year, and the rest of the page is a tasklist. Tasks may be transferred from the previous month's incompleted tasks, or abandonned.
Moreover, pages are (manually) numbered and the first sheet of the notebook is reserved to index pages I might need to refer to later but do not warrant a physical bookmark. A personnal organizer, a journal and a notebook can thus be united in one Super Organizer.
