When I'm really blue, I like to read the food essays of M.F.K. Fisher and Calvin Trillin, interspersed with bits and pieces of the Dalai Lama. Something about the combination of calm, cheerful, non-saccharine spiritual philosophy and food porn cheers me up every time.

I also love Winter's Tale more than any other book I've read, and re-read it annually, usually right around New Year's, for reasons that are probably obvious to you. (-:
