@Rasp bit more specific on what kinds of ideas you looking for? How to entertain yourself? How to support yourself? Where to go?
also, where do you live, like which country and rural or urban? what are your skills and interests?
without knowing the specifics of what you mean, some of the first things that came to my mind is look into DIY culture... there's a hell of a lot that can be done without money...
ever heard of woofing (work on organic farms for food and accommodation), lots of similar things like help x, house sitting websites, is couch surfing still a website?
volunteering is great way to meet people, learn skills and access resources, also of course helping people doing something you are interested in doing is very rewarding...
mediation costs nothing ;-) www.dhamma.org
hope some of this helps, happy to throw more ideas your way if ya give a bit more specifity...
