When I land in a country and they ask for 'occupation,' I always just put 'artist.' I think that covers all of it.
Usually the characters I play are men of few words, who communicate in non-verbal ways.
If there's one thing I've learned from traveling, it's that it is definitely more important how you are than where you are. You can say, 'Oh, I hate X city, I hate that country, or I prefer this city,' but it's a little bit up to you to find some kind of happiness.
Be kind. It's worthwhile to make an effort to learn about other people and figure out what you might have in common with them.
