As with all things, often it doesn't work out and what you could end up with is (worst case) stuck somewhere in Asia with no funds, job or house.
This sort of thing works if you have no family. A few years ago it would have worked, now with a young daughter and fiancee it's harder. And then when you're living on that beach and you meet a girl? Are you sure you want to live there for a long long time?
One day we'll travel and live around the world, but I suspect much later. So.. sour grapes!
