There is a reason people make resolutions on New Year's Eve, and I don't think it's just because it's a new year. New Year's follows the biggest economic shut down that regularly happens in the west - i.e. the most sacred time in our calendar. This naturally makes room for reflection and a desire for growth, catalyzed by contemplation of God become man (or, at least spending time with family). This in turn makes us better people, able to do more good. We should take this kind of time out more often; maybe we would find ourselves less prone to bias, sunk cost, burnout, and lack of vision.
Happy New Year, and Merry Christmas for 6 more days.
