Let's start with the easy stuff. It gets dark way too early in January.
And it is cold, bitterly cold.
During the first 2 weeks of January, you are a one-in-a-million blob of over carbed, under rested, out of shape hordes all hoping and praying for the will power to carry you to February.
Either from coming down too hard from your holiday high or trying to shake off the sadness many experience this time of year, you're struggling.
Looking at the deeper stuff, it doesn't show a glimmer of hope.
