Now, I'm not actually using my planner for appointments, we have an Outlook calendar that everyone uses, which is convenient for scheduling appointments. I found myself constantly making little to-do lists and keeping notes in different notebooks, and I finally got tired of trying to remember what cute notebook I was using during such-n-such meeting. And after switching my Plum Paper Planner into an A5 binder, I've loved being able to add different things into my binder, like notes, lists, etc.
So I took to Etsy to find an inexpensive personal planner that I could keep my lists in. I wound up purchasing a red one from washibear after reading some good reviews on them from instagram and their shop page. It's a great planner for the price; I was pretty impressed by the quality.
Once my binder was headed my way, I considered my options for inserts. There are tons out there on Etsy, but I decided to just make and print my own. They are really simple with a spot to write in the date, the day of the week, a place for notes, and another box with the days of the week where I can list appointments. I use this just to write in who I met with on what day, so that if I ever need to reference something, I have it easily. As mentioned, it's not used to schedule appointments, so I do not write in times or locations, but of course you could.
Mostly I write out my daily to-do list and I update it and add to it through out the day. It has helped so much in remembering what I worked on which day and which things still need to be done.
Here is a link to the PDF inserts. I print these double-sided, cut, and hole-punch. Sometimes I'll add a strip of washi tape to reinforce the holes. For reference, the boxes are sized to an Erin Condren/PPP/Happy Planner width, so you could use stickers to decorate. Enjoy!
