Ok so I love calendar journaling and I did it for years. In high school my best friend started writing down everything we/she did on her wall calendar in her bedroom. It rocked so I started doing it in my Franklin planner, on the monthly pages. I did it all through high school, college and my mission. It's so fun to pull them out and look back on things I've done that I would never remember other wise. Like dates that totally sucked and are very laugh worthy now and great girls' night out moment too.
I'm taking it up again, it's a quick way to record events and I can go back to journal more later too if I want to. Plus I'll be able to remind the kids of things we did when they complain as adults of never doing anything - cause that's bound to happen :).
