I'm going to get on the blogging bandwagon and drop the 'it' concept of the moment: hygge (per wikipedia: a Danish and Norwegian word [describing] a quality of cosiness and comfortable conviviality that engenders a feeling of contentment or well-being). Leave it to those with long experience of serious stretches of cold and dark to come up with such necessary vocabulary.
Anyway, you can skip through the interwebs at your leisure, calling up all kinds of intoxicating examples of the hygge philosophy. It's the perfect concept for December; for Mercury in retrograde; for the inevitable, inescapable need to turn inward, to slow down or else risk health and happiness at this, both the darkest and most festive time of the year.
It's a marathon, petals. And like any elite athlete knows, these moments of endurance require a keen eye toward your own well-being, your own need for rest, for quiet, for no-apologies solitude alongside the warmth and festivity welcoming back the light (and, in an astrological turn of synchronicity, the solstice arrives one day before Mercury goes direct).
This year (especially this year) has requested this slow-down, this period of restoration, of recuperation so that we can remember the highlights of 2017--those moments begging not to be forgotten amongst the detritus of what was, for all of us, a very difficult year.
