Without a doubt Mongolia. I love the terrain and wide open spaces that have remained relatively untouched. The difference from where I live now and there is night and day. It also seems pretty cheap to live there so I can probably just telecommute and live very comfortably.
any Scandinavian country tbh, but probably Sweden. Great healthcare, jobs, pay, quality of life standard, amazing nature and it is not too fucking hot (I love the cold)
The social security in places like Denmark and Sweden also mean that you don't really have to worry about getting ill or falling on hard times as the state will step in to help out, which should be the way in modern social democratic countries.
