Some people really enjoy the gypsy style of life of moving at will when they want and working when they want, I've met a few up here in Alaska, hired a few for odd jobs and such
One day, I would like the possibility to travel through Australia with the family for a couple months, blogging for petrol and food money :) Wouldn't that be awesome?
Then there are the people who don't mind being on welfare in the States, it provides almost everything for them and they get to stay at home, smoke, drink and do whatever their drug of choice is.
I wonder how many of them are actually happy?
I find that a perfectly acceptable reason/meaning for/of life.
I think if done intentionally and knowing the cost, there is nothing wrong with it. The problem is that many are raised so heavily into the process that they do it blindly - yet still have that itch to scratch in other areas - but they can't locate it.
I know a few, and they are no less happy than most people, like most people they kind of want a better life, but they are enjoying the freedom their choice gives them. Some of them if they want a few extra bucks, they chop wood to sell, or help clean lots, or clean fish. But mostly they just enjoy the life, they can go pick berries when they want, they can fish and hunt when they want. They are a lot like retired people, happy with where they are and free to do when they want.
There are people who do that in Australia and surf out the back of a van. There is one important difference with retired people though - a retired person has lived a life and got to that point, a younger person might not realize there are things that they might want later in life - but they no longer have the path to get there.
