The wise old gnome that lives in my mom's indoor plant-garden recently came to life and gave me step-by-step instructions on how to beat the winter blues*:
1) Do something nice for someone else (Baked goods are, in most circumstances, much appreciated and also fun to make).
2) Read a good book (and take suggestions from a friend. Mine is 'The Raw Shark Texts" courtesy of the lovely Ms. Lauren Sieczkowski).
3) Drink Swiss Miss! (And load it up with whipped cream)
4) Visit (or call if you can't visit) your Mom/Grandmother/other-lonely-relative who misses you dearly.
Repeat when necessary!
