I highly recommend hanging the lights. If you can put them on a timer (they're cheap) so they come on right before you get home, even better. I'm *immensely* cheered in this dark season when I come home from work to the glow of the tiny white lights on my porch.

And then, manybe ... don't try to *do* so much? See if you can make some time just to sit in peace, listen to some good music (holiday or otherwise) and just *be*. Finding such small moments of silence is really helpful to me when I'm reaching too hard for the cheer...
