That's my story and I'm stickin' to it.
I am a big advocate of anyone entering into sustainable living by simply dropping their present life and moving onto a piece of land with next to nothing, and frankly not even much of a plan. It's what we did roughly 24 years ago. That method shows you what you are made of, and clarifies your personal set of needs (everyone's are unique). In a general sense it has worked out well for us, and though it has taken quite a while, in many areas we have achieved serious success. Besides, if we had waited to begin living sustainably until we had all our ducks in a row I doubt we ever would have.
