eHow: Experiment with the freedom of buying nothing and embrace Henry David Thoreau’s sentiment that “he who owns little is little owned.”
Practice reverse snobbery. Express contempt for people who mindlessly buy things. This has two benefits: It raises the act of not buying things to a lofty moral height, from which you can denigrate others, and you get to enjoy the irony of simultaneously being a snob while making fun of other snobs.
Take pride in being an eccentric recycler.
