Use page flags for future planning, to list reoccurring tasks (zone cleaning, weekly planning & reviews, change filters, etc.) or to write down appointments that might need to be rescheduled or cancelled. I use them in each of these ways and I use them as tabs to mark important spots in my planner. The best part is that they are repositionable so I can easily move them around if I need to. They are fairly cheap and can be found just about everywhere (WalMart, Target, Office Depot, Staples, Amazon and most grocery stores). Happy Planning!
