I have a monthly one magnetically attached to a whiteboard… and I LOVE IT!! Had it about a year and it’s saved my life. It’s tangible, but not in a notebook. I don’t have to remember to look at it because it’s in my bedroom and I see it automatically. If I need to, I can take a picture of it on my phone so I can remember what’s on it when I’m out and about.
Also, one benefit of this rather than notebook calendars, is that I don’t feel so bad if I don’t use it for a few weeks. In a notebook, seeing all the blank pages would discourage me. But with this… I wipe it off every month and it’s a brand new fresh start! Honestly, it’s the absolute BEST tool I’ve found for keeping appointments and organising my life.
One key thing to remember is to put as few things as possible on there. The fewer things you write on your calendar, the more likely you are to remember them, so only start by writing essential things. That’s why I have mine attached to a larger whiteboard - so that underneath, I can write other things like shopping lists and to-do lists. Any important letters relating to the appointments get shoved at the side of it. Here’s a pic! (Don’t worry that I haven’t added on the last dates, I left the numbers there from February to cut corners…)
