How do you handle the "blahs"?

January and February are historically tough months for me. As much as I want to enjoy winter and all that comes with it, I have a hard time doing so. The short days and cold weather get to me, and I have a difficult time staying motivated. Over the last few days in particular I've been feeling exhausted and I know that it is because I'm not being as active as usual, and I've barely left the house in weeks.

I'm trying to keep my mind present for my kids and to be here for them as I know I need to be. Having us all together each day, everyday, makes it all the more important for me to not let myself get swallowed up by the winter blues that normally affect me at this time of year. I'm struggling, though, and I feel like might loose the battle at any given second.

A question for you, my (two?) dear readers: What do you do to stay motivated and not let your homeschooling or unschooling suffer when you are having "blah" days and weeks? Do you have any special things that you do for yourself or with your children?
