The start of a new year is an event that millions of people use as a marker of a fresh start in their lives. It’s an opportunity to be better, to do the things we should and to set aside the missteps of the previous year. The appeal of it makes sense; there’s a clear demarcation between the old and the new, a literal turning of the page in the case of those wall calendars that still exist. A cynic might argue that it’s no less arbitrary than any other date chosen as the start of the “new you,” but whatever the reason, the first days of the new year have special power in our minds as the time for reinventing and reimagining our circumstances.
