Your planner’s daily note pages are your collection point for unprocessed tasks. As you take notes, place checkboxes next to pending actions that you collect. Do not put them in a special section, just include them along with any other notes you take for the day. You will put these tasks in their homes when you process your notes.
Place a paper clip on the oldest daily note page that may have unprocessed tasks (unchecked boxes). This is where you continue processing next time.
Make sure your planner layout is correct.
