Links to what work is available, how to get it, what to expect in pay, and their links to many related topics.
I've said a lot on this topic in my "Retire and Travel" section on the old website. Other than what's there, I can point you to a number of sites that will help further. I've found many, many sites where these topics are treated ad nauseum, so here are two of the best. "Movin' On" tries to sell you their book, but also has a free newsletter and many interesting links. The "HitchItch" has links to these two and a large number of others with travel journals and other RV-related ideas.
Well, as I see it, there are only two ways to retire early -- you either make a bunch of money or you plan to live more cheaply after retirement. As I have few ideas on how to make a bunch, I've concentrated on living cheaply. One way is to go full-time on the road -- another is to live in a foreign country -- or live on a boat. Below are links to some sites where you can learn more.
Living in a Foreign Country
There are probably many sites that treat this topic, but this one below caught my eye and seems to offer a wide variety of options.
