I love to stay inside during winter. Thankfully I work from home so I don't have to Trudge through the snow and ice to get to my car and get to work.
I just walk a few feet to my computer and do my work there.
Then whenever I like to I can just plop down on the couch and watch TV or take a nap.
I slow down during winter and lose energy. When spring comes I'm more energetic.
