A lot of the UK expats I meet in my travels give me the whole spiel about how they were so fed up with the UK. Then they start in on their new home and how fed up they are there. I'm not sure being fed up is a good reason to leave. So many people are 'fed up' with things that are universal or worse at their destination.

I met an American who went on and on about being fed up with the bull in the US. So he chose to be an ESL teacher in Thailand. He isn't allowed to smoke at his school, not just in the buildings but within sight of the campus. He has to wear long sleeves in class because he has tattoos and they have to be hidden (note that classrooms are not always air-conditioned and it goes above 40 where he is, so long sleeves really are a problem). He thought American women were money-grubbing and came to a place where western men are looked at as bank accounts.

My point is, examine what really bothers you, and do some research first.
