Decorate simply and modestly, if you feel you must decorate at all. You could make decorating a family project by popping popcorn and string the popcorn with cranberries and have an old fashioned Christmas. Meanwhile play Christmas music, tell Christmas stories or share Christmas memories. Give yourself permission to invite everyone to your house this year so you don't have to run all over town. Make it a potluck or a combined effort.

Consciously choose the events you will go to. Know why you are going. It's OK to say no. Even too many good events can get stressful. If you have a new family configuration this year due to a divorce or death or kids leaving home, feel free to develop a new tradition.
