Christmas is a time to remember. It is also a time for presents.
How about giving yourself the present this Christmas. Don’t dwell on times past. Just be present and enjoy what is actually happening. You will have plenty of opportunities leading up to Christmas to create memories for the future. The best way to do this is to dwell on the present. Do whatever you are doing as well as you can with minimal rumination or mind chatter. If the chatter starts just quietly go back to what you were doing. Listen when people speak to you. Pause before replying. Notice everything around you. Really notice. Observe. Feel. Think less.
Make this time the best ever by being really present in everything you say and do. Give the chatter a holiday.
