January Blues

My kids have cabin fever. It's cold, it's wet, homeschooling is boring, why do we have to get out of bed?! Well, I can't help the cold and the wet. Schoolwork isn't boring; they just aren't motivated after taking a holiday break. And I don't want to get out of bed either, but I have to make money and feed my lazy beasts. Does anyone have a cure for the January blues?
