So there are all these ways of living, and moving about the world. And I like to do the same, but more importantly, I'd like to emphasize just how do-able it is, and to serve as a sort of waypoint where these folks can pop in to compare notes, or in most cases to take the notes myself and to compare notes for them. Because each person, despite their drastically different approaches, can learn something from watching others do it.
Sometimes, it's just enough to know that you could just walk. Right now, if you wanted to, and keep walking, and not just survive, but thrive. And that can alone can take the pressure off of everyone's everyday life.
