Winter. People hate it, people whine about it, people get depressed (literally) because of a lack of sunlight. I've gotten depressed over a lack of sunlight. For five years in North Carolina I was a depressed, hibernating, lazy mess for all of winter. Sure, Winter in North Carolina lasted like five days, but man was I miserable those five days.
You'll all be happy to know, I've figured it out. It's not the sunlight! It's unwillingness to go outside. Depression over the cold - not the darkness, the cloudy gray skies - the cold. And do you know what? Layers make the cold ok, they make it bearable. They make it possible to go outside and run and frolic through the snow. They make it possible to run 4 miles with your dog, and watch her leap and dive through snowbanks created by snowblowers. They make it possible for people to yell catcalls out their car windows as they drive by. For me, getting out there makes the difference. It can be the middle of a snowstorm in 28 degrees or a gorgeous, sunny, negative 5 degree day. It doesn't matter - if I don't sit on my ass all day - if I don't sit inside and mope - I can thrive in winter.
All figured out. w00t! So here's a little snow for you.
