I would choose the job I do now.
If I could, I would like to be a physicst as well as a poet, that I could do research on objective world that I am interested in together with writing poems to discribe the beauty of natural world and express myself inside.
The only thing that I really enjoy is learning languages. So I could be a teacher, but I'm afraid the only language I can teach with confidence is my native one. But not too many people want to learn it seriously anyway.
So I might just turn into a hippie eventually.
Tourist Guide for sure
The kind that Bear Grylls or Ace Ventura have. :D
