Get witchy with it
The time of the solstice is also known as Yule for Wiccan and Pagan practitioners, but the celebration of light has permeated general society - you've heard of a yule log, right? Even if you're not particularly spiritual, Yule is the ideal time for meditating, reflecting, setting intentions for the new year, and embracing change. Since you probably don't have a wood-burning fireplace in your apartment, lighting a few candles will do just fine.
