Once when I was using a Classic (U.S. Junior / roughly A5) Franklin Covey binder to organize my life and various jobs, I wished for a binder with a shoulder strap so I could carry the whole thing instead of a purse. After all, everything I needed to get through the day was in there!
Once I saw a picture of the actress Diane Keaton with a Personal-size binder stuck into her belt.
Sometimes I find hand-carrying my Filofax with me works fine, as long as I'm not carrying anything else in hand.
How do you carry your organizer?
Of course, since it's Friday, you can go off on any conversational tangent you wish!
