An amusing essay here:
There are millions of Americans just like me living outside the United States. Living lives much more fulfilling, peaceful, free and abundant than we ever could have attained back home. Some of us happened upon these lives by accident – we tried a year abroad and found that we liked it – others made a conscious decision to pack up and leave for good. You’ll find us in Canada, all over Europe, in many parts of Asia, in Australia and New Zealand, and in most other countries of the globe.
