Gretchen Rubin writes eloquently about the return of her lost Filofax. (No surprise, she's the author of a forthcoming book called The Happiness Project.)
Here's an excerpt:
I’m old-fashioned when it comes to keeping my calendar, and I carry around a worn, fat Filofax that contains every piece of information I need to live my life: my calendar, addresses and phone numbers, class lists for both girls, business cards for doctors, repairmen, etc., a list of important birthdays, a subway map of Manhattan, and a few precious mementos, like the Valentine heart the Big Girl made for me when she was in kindergarten.
But it's worth clicking for the illustration alone.
