There are a few activities that have traditionally been my fallback favorite things.

-Art (making it, or taking it in, in a gallery or museum)
-Travelling (anywhere, any way; just give me an excuse)
-Cooking (feeding people great food is particularly joyful for me; a family trait)
-Reading (have had trouble with it since I became depressed---I want to get it back very badly---but I was an avid reader)
-Going junking and antiquing (It is fun & relaxing, and educational)
-Finding great small treasures of restaurants---places where the food is heavenly and the prices extra cheap!
