My memory is made of teflon, it's a common disorder for people who are brain-workers. I forget meetings, reporting students on vacation, and all those small things I have to fix to make the world go round. A planner is essential for my daily life and I've concluded that google calendar doesn't work for me.
To keep my stress level down, I use mini post it notes for "to do" tasks. I post them in my planner, and when I've finished each task I throw the notes away. I can also move the notes to another day if something more important comes up. That means I only have to focus on one day at a time, being present, carpe diem and shit like that...
The problem with prefabricated templates is that they sometimes doesn't fit your needs. My teachers planner worked just fine, but I thought it was a little bit boring and limiting. After some good advices from my sister in law who also is a teacher, I bought a planner from Simple stories in A5 size. I liked it because of the pockets, the dotted lining and the size. But the main thing is that the ring opener is making you able to personalize it more.
I bought mine from Skaparlusten. I can highly recommend any swedish people who likes stationery this shop, because I got my parcel within two days. And she called me the day after I put my order because one of the items were out of stock. I told her to change it with something that fitted the rest of my order and she sent me the clips and inserts for the planner.
I wanted my week plan to look more like a schedule than the horizontal one that came with the planner. Publisher is an excellent office based programme that is easy to use, making templates. I kept mine simple because I'm supposed to alter it for every week.
If someone is interested, I have this template in pdf-format to send to you. Note that you print it on A4, divide the paper in half and make your own holes fitting your planner. Oh and if you like, I can change the days to english or change the fonts, easy peasy.
