I have Filofaxes for various things, addresses, financial etc but I carry my diary in my everyday Filofax which is my personal, purple, patent original. I have been using this as my main planner for over a year and it still looks good
The front of my planner holds pens, post it notes and a home made flyleaf.
I have a few of my blog cards in a card holder near the front of my planner.
In my Filofax there are various pages of information including local library opening times and also a short list of positive phrases. There is a place for notes and a small notepad in the back.The superheroes postcard came from Paperchase and I use it as a divider. I also have various diet related pages to track my eating.I carry only the things I think I need and do need when out and about and can change things as and when I want. The luxury of a ring bound planner system is that you can add and remove whatever you need.
Despite the 1980's comments and jokes I receive regularly, the ring bound planner is perfect for me and also for many others. It is a really good system for keeping organized and in control.
