I just recommended the blog Becoming Minimalist to Simon, asking him to start reading it along with me. I don't know why I waited so long. It is probably one of the most thought-provoking blogs I read, and has honestly changed my view on life over the last few months. I am constantly amazed at how much minimalism and the teachings of Jesus seem to coincide. I'd highly recommend it to you as well: Becoming Minimalist.
PS-- what are your thoughts on having an online garage sale?
