Just a side note - you absolutely don't need to be millions rich to travel for extended periods. You just need to have few financial obligations that are location dependent.
In an extreme example (which some of us fantasize about), you could have all your necessary possession in two bags, have no "home" (and no car and no other anchors), and travel the world for less than many people spend living in one place. This is especially true if you take a US/EU salary and spend time in much lower cost of living places.
