I recommend these things for this busy season:
Read a few verses: Like these
Do some yoga: yoga with Adriene is my favorite, and here's one just for stress relief.
Read a seasonal book: Shepherds Abiding by Jan Karon, or The Dark is Rising by Susan Cooper
I listen to both on unabridged audio every year at this time.
Fold some paper: whether it's these fun origami stars, or wrapping presents while watching a holiday episode of your favorite show, a bit of 'paperwork' can be good for the mind.
Watch a Christmas movie: old classics, cheesy new ones, or obscure ones like this: A Child's Christmas in Wales, based on a Dylan Thomas poem. It's delightfully cozy and atmospheric, with a nostalgic sense of place, and has found its way into my personal Christmas traditions.
Light a candle or two, or eight: Today is the sixth night of Hanukkah, and while I don't always get around to lighting the menorah, I love to remember God's work in that story, his promises. An extra reminder, as we light our Advent candles too, in wait, but also in joy that our Messiah came.
