So how did I grow up to be so organized (unless under stress)? Really I don't know the answer.
Perhaps it started with wall calenders. I loved receiving the World Wildlife Fund calenders in the mail every year and my Harry Potter (TM) calenders. Kept them all stored by year in a folder until its final trashing three years ago. But everything was on those calenders: marked appointments, assignments, holiday closings, eBay shipping times, cat birthdays, web postings, virtual events, etc....
