I like to toy with the idea of using my day per page diary as a planner + journal. My daily book is with me all the time so it's a natural place to capture those memories before they escape.
Currently I'm using my Quo Vadis Notor, which I like because the schedule is at the top and out of the way so I can use the lines below for lists and journaling.
My new 2013 Moleskine Magenta large daily planner is so pretty, it got me thinking on how I could use it next year. With the larger page size I could have a column at the left to see my entire day chronologically, have a space to the right for to-dos, and still have a large area of the page for journaling (click on photo for a better view):
I probably wouldn't even actually draw the lines, but just use these areas in this way.
I admit this setup is a lot like the format in the Quo Vadis ABP1, which has a timed column at the left and the rest of the daily page lined for notes and lists. But really you could use any day per page planner in this way.
Does anyone else like to journal or jot memories directly onto your planner/ diary pages?
