I have a buddy who apparently took the 4HWW to heart and moved to Argentina to work as a freelance software engineer... he seems to be doing well.
Personally, I thought Ferriss made it seem a little easy, but who knows? Did you actually do all of the challenges? I guess you can't knock it until you've tried it.
Does your buddy need to travel back to consult with customers in the US (assuming that is where he is from)? Was he an established consultant before the move?
He does have to travel to meet with clients, but from what I've gathered, it is not particularly frequent. He had a pretty solid resume as an engineer and is definitely one of the most creative, smart people I know, but I don't think that he had much of a list of prior clients. As I recall, our school kind of set him up with his 2 main clients. Its quite a bold move on his part and inspiring to me. It's only one data point, but its certainly an example of how its possible to carve out a niche.
i took it to heart and am now living in Buenos Aires as a freelance software engineer. I communicate online with my clients, and work on my own projects with the free time that euros/dollars -> peso conversion gives. I recommend it!
