Despite all the horror stories you read about on forums, there are also 1000s of people who remain 'in-country' and really enjoy their jobs too. There are plenty of posts on forums from people who make teaching abroad sound terrible, but there are also plenty of blogs and even books, from people who have gone abroad to teach and never looked back. Forums tend to focus more on the negative IMO.

Of course there are many pitfalls in working away from home, and some people will seek to take advantage of that, but there are also many places that, and many people that dont. There are also many people who head off to work abroad who are ill prepared (thats not going to help) or just not suited to work and/or travel. Another thing to remember is that forums are a good place for people to let off steam, to release their daily gripes. That doesnt mean those complaints arent real, but it does suggest that people are more likely to post something about a bad day than a good one.
