Where are you going to? Because if it's Thailand or some other third world place, the advice would be different from that for a European country.
Do you speak the language of your prospective new place of residence?
Personally, I would use the holiday to research the concept of living abroad, but but not make a change on that basis alone - without coming home and thinking it through thoroughly. A country wherein you enjoy the holiday of your dreams will not necessarily be the place to relocate to and spend the rest of your life in.
