Yes. I keep what has evolved into some sort of log book of my days. I did it because I always write things-to-do and reminders on post-it notes. I used to throw them away, but realized I had no idea what I did with my days. Now I tape them (post-it's lose their sticky after a while) in the notebook along with handwritten notes. I occasionally scan the pages and put them on dropbox so I can easily flip through old notebooks if I need to find something. Square ruled notebooks happen to be the only way I can keep my Seinfeld calendars going, too.
