If you haven't done so already, mark off the calendar and set aside some time in the next week to write some holiday cards to the people in your life. While you may usually send out cards each year to a certain group of people, why not extend that list by one or two this year?
Think of some people in the service industry that you rely on each year but might not have thought about sending them a card in the past. You know that friendly guy who always does your oil change? Or the staff at one of your doctor's offices? Why not send them a card? This is a great time of year to say "thank you," and the list is endless of people we can and should thank.
If you aren't typically someone who sends holiday cards, try beginning this ritual. I believe there aren't enough positive rituals we practice that bond us together as a community. Now is a great time to start!
