New Year’s resolutions are like going to a dentist; it seems productive at the time but a month later nothing has changed. So forget resolutions. Instead, get with your partner and create a vision for your shared future.
Where do you want to be/say/do next year that you cannot be/say/do now? How can you work together to make this vision a reality? What is one step you can take now to get closer to that vision?
Then, once that step is done, get together and figure out the next step. Not only will this make you feel better (you are creating small successes with each step accomplished),
your relationship will be stronger at the end of year because you worked together.
