I personally love the idea of making resolutions, whether at the new year, or many of the other times we have to do it. For instance, each year at your birthday, at Advent (the beginning of the Church year), during Lent, at the beginning of a new school year, at the beginning of each new season, etc.
It's a great idea to resolve for the next season or until next year at that same time, you're going to do something different. The years, the seasons, the shorter chunks of time are all a perfect time to start anew. I love the idea of rebirth, a new start, a clean slate. It's why I love butterflies. It's not that we constantly are failing or that we have to throw everything out and start over all the time. It's the idea that life is a process of renewal, change, conversion. The idea that conversion is both a moment and a lifelong event. I know I need the chances to remind myself of resolutions, changes, things to "lean" into. It's fun to check in at these different parts of the year, to make use of the different calendars that rotate simultaneously and to see where you were at the last check in.
God's mercies are new every morning. (Lamentations 3:22-23)
Here is a great article about what to do before the New Year.
