I live pretty simply - most of my friends are amazzed at how minimalist I am. In additon to my bike, I have a few clothes, books TV, bed, and futon, and a few other odds and ends (pictures, etc.) I get most of my media materials (books, DVDs, etc.) from the library.
My last great indulgence is cable TV. I'm trying to work up the discipline to cancel the cable, and realocate that money on a gym membership.
