It always sounds like a great idea. But… moving away from the USA is not all roses and champagne. You are going to a totally new place. What about friends, family, connections? The health insirance. The language? It can be isolating; how will you meet people?
Another approach to consider: move to a lower cost area of the USA and then travel different parts of world. Then come to home base. Rest & relax. Spend the holidays. And then repeat.
