Many years ago, before I was married or "in a relationship" I had a personal "tradition". I used to deliberately go into work between Christmas and the New Year. The roads were clear, I would set off late and still get into work early. I used to do loads of "housekeeping". In particular I used to delete  clutter from my personal data spaces. I saved "holiday days" and it didn't make much difference to my social life which was mostly in the evenings.

This was also a good time to reflect on the past year and make plans for the coming year. Thinking of it now, this last activity was rather like what is meant by the Roman god Janus (https://en.wikipedia.org/wiki/Janus )
