I got lax this last year on staying organized and it bit me in the butt, so I've started early to fix that. Not only is my Franklin Covey planner already marked with Craft events, birthdays, holidays etc, but I just sent out the 2008 dates of my Witches' Meetup to all members.
Strangely enough, I'm MUCH calmer when I've got everything under control like that. Some people go nuts trying to schedule things; I feel myself getting almost Zen-like the more I have a handle on the basics of life. I'm not obsessive about it by any means, but not running about like a crazy person trying to please everyone helps a lot, because I just point to the planner and say, "sorry, booked."
What's going to be especially interesting is sending out advance notice of Esbats (every other Saturday) to some of the more spontaneous in-laws. It's one thing to accept our faith, but they've never really had to deal with "sorry, we have religious services, can't make your event that you called us about 3 hours before it occurs." The whole day is focused on the Esbat evening, which not everyone understands. But this year they can't say they didn't have a heads-up.
Yes, I know that's not the standard pagan mode. But I never claimed to be a standard pagan. ;)
