Poland grinds you down after a while. In the end you have to take a I dont give a crap attitude just like everybody else. If you cant beat em join em....
Or you can escape back to civilization.
You said it best...Poland grinds you down. The locals are so beat down by it they don't even realize it half the time.
Expats stay in Poland for two reasons:
1. They have a Polish spouse/gf etc
2. Their money goes farther (and this is one is becoming more and more untrue as prices in Poland have gotten stupid)
Notice there is nothing on the list saying how wonderful the quality of life in Poland is...because it's not. Most every expat I know really doesn't like the place after a few years at best.
