If your dream has always been to see the world, there are a few careers you can choose that will allow this dream to come true.
Look for gig-to-gig jobs, like touring as a musician—either in conventional venues on land, or on a cruise ship. Depending on your language skills, you could also get work as a tour guide, a nanny, or an au pair. Another option is to work in education. You could teach English or maybe another school subject overseas—again, depending on your language skills.
