A friend of mine did that except he went a step further and committed to not even ride in an automobile for a year. He lives in a remote location outside the nearest rural town, so I was skeptical but he did it. He said he got a lot out of it. The thing that stuck in my mind was that he said he developed a much clearer understanding of the differences between things he wanted and things he needed when either one involved a 20 mile round trip bike ride to the nearest store.
