This is a question I've been asking myself a lot over the past few years. I've been getting by with very little money myself, and while it's been been very difficult, I do think it's possible. Especially for someone with no addictions, who is truly willing to work in exchange for needed goods and services. Anyway, something to think about in uncertain economic times.
Heidemarie Schwermer Has Been Moneyless For 16 Years
"How does she do it? Schwermer barters a few hours of cleaning and gardening in exchange for food. For shelter, she wanders from place to place offering small services for a bed. Sometimes, she relies on the hospitality of people she meets along the way. Her friends occasionally give her clothing, so she keeps what she needs and donates anything that's too burdensome to carry around."
