Lately I've found I have multiple concerns in my life -- work, family, two different volunteer organizations. Since I use 1 day-per-page, I can fit it all on one page, but I've found it helpful to use different colors -- blue for anything personal or family, red for work, green for volunteer. In the past, I've kept different concerns in different organizers or sections.
What's your favorite solution for delineating multiple areas your life in your organizer?
Of course, since it's Friday, free-for-all discussion is welcome, too!
