Secret santa always works for me and my co-workers to help get into the spirit of Christmas. You could try (if you have a partner/ boyfriend) to make presents, instead of buying them. Hang decorations in your house, BAKE COOKIES in the shapes of Xmas stuff! That would be so much fun! And you can share them with family and friends to help spread the joy!!
I find once I start getting the decorations up and get working on making some presents, I start getting some Christmas spirit. Once December kicks in and some snow covers the ground and the Christams music gets going I start really feeling it.
May i ask what is that spirit?
