Organizing for Christmas

I really appreciate the tips for organizing Christmas from Echoes of Laughter.

Her secret is to "start early, give yourself deadlines, and do only the things you enjoy - let the rest go!"

I got some great tips for her. Specifically I have set the following deadlines (I had months in before but that seems too vague for me).

Christmas Cards - in mail Dec 1st
Christmas Decorating - outside lights, wreaths Nov 20th; inside decor Nov 26/27th; tree Dec 4th
Shopping Complete - Dec 10th
Gifts wrapped - Dec 15th

Totally do-able, right? How do you organize yourself for a less-stressed Christmas?
