As we become more of a global society and telecommuting is more available with the internet, I have heard more and more people choosing to live abroad for at least a little while. This is something that I have considered for some point later in life when the kids are a little older.
However, there are people who seem to just liquidate almost all of the tangible possessions that they own, and move away. There are two people who I know from HS who have not lived in the US for at least 5 years now and when I ran into one of them this summer, she was very different than she was in HS. Another friend of mine just left for a year in China doing volunteer work as a teacher with a church mission. I think it will be a good experience for him and will teach him a lot about life.
However, I think that we as a society become so attached to our tangible positions, that it is often difficult for us to fathom the idea of selling it all and starting fresh in another state, not to mention another country with a different culture and possibility another language. Then there is the idea and reality of obligations here in the states. You can sell a house or a car to get rid of the payments, but student loans and credit cards are not as easy to get rid of and need to be paid back.
Could you do it? Could you sell off almost everything you own and you and your family only keep the stuff you can carry? Could just pick up and move to another country? If so where would you move and why? Would it be a forever type of thing or would it just be for a few months to a year?
Personally, I could liquidate everything I own and move (once the student loans are paid off). If I did, I would want to end up in Northern Italy or somewhere in Central America like Costa Rica.
