The Arc is the best invention for Anal OCD people. Only available from Staples as far as I know. You can choose your cover. Choose your notebook or calendar pages. Choose the size rings you want. And you can take pages out, move then, insert more easily. You can even make these cool little half inserts. The possibilities are endless really. I've seen so many ideas with it. I use it for my daily planner.
FYI - the lighting sucks really bad in my kitchen when I don't have a sunny day providing good natural light.
So I have my months and calendar pages (that I make, see below). I also have additional sections, Fitness for you know, logging fitness stuff. Future dates, for things that come up for the next year that no one will remember without writing it down. I have a Books section I write books I want to get, look in to or get from the library for both myself and A. I also have a To Do Later section, for non-urgent stuff I don't want to forget about, but I also don't want it in my face daily. You know, I'll come find you when I want you type stuff.
See that funny little half page I stuck up so you could see it, I punch that so it sticks up about 1/2 inch above the other pages and that's my current week I'm. So when it's closed, that sticks up so I can quick open to the right spot. And I use it for quick notes I jot down.
I use Arc's other pages but I do print my own calendar on thick card-stock. Mainly because I do not think anyone makes a calendar for my Anal OCD ways. I am not one of those people that can have a calendar in one spot, notes in another, a chart on the wall for school stuff and some other binder for meal planning. I have to have it all in one spot, or things get missed. Really badly. I like it quick, easy and all in one.
Here's a close up of one day. On the right is pretty self explanatory with the Meals, Bills and School having their own space. I also write meals in blue, bills in green and school appointments and activities in red pen. Is this normal? I'm certain it is.
On the left, is everything else. Written in blue of course, daily reminders and to do's. Any appointment or important date gets written in red so it stands out. At the bottom I write all friends and family's birthdays and anniversary's in purple pen.
Overall I have been more than impressed with this system. They have several different types and styles of covers and pages to choose from in both half page and full page options.
