thats a bit strong bud.People that attempt this sort of thing never realize what they are up against. Chris McCandless springs to mind. In spite of the fact that hollywood tried to make a hero out of him and the internet doubly so... the outcome was predictable.
Internet videos and BBC heroes never show what is going on off camera and their shows are scripted as entertainment. I know, I have made videos too. In one of my videos I clean up the ruffed grouse in a matter of seconds but there is no way to show that it took 3 days to get the damn thing.
Most people want to live in Walt Disney land in one way or another and want to believe in magic, others want to live in Henry David Thoreau land. You cannot do either permanently, only until the money runs out.
There is nothing wrong with a few weeks here and a few weeks there out in the bush or a well thought out retirement strategy that allows you to live there but we can no more give up the modern world than we can go back in time.
im with you, it is a lot more harder than people realise, if it wasn't we would all be doing it.
but I think if someone really wanted too give it a go, and it worked for them, then great, until he try's he will never no.
