How do you travel the world and work?

I keep reading that you are a digital nomad which I am only 30% of the way to understanding what that is.   Is it you travel for work and get paid in your local currency? I recently finished college in New Hampshire and I want to see the world and get out of the cold.  How can I do that and not live like a street person or hobo? In your blog posts I see you've been to Spain, Portugal, France and Italy, all places on my bucket list.  If I got a one way ticket to either of those places could I find work in either teaching English or maybe being an assistant?  I am decent with computers, writing and manual labor.  I don't really have a big resume since I just left school but I did intern in office for a few months. I appreciate your any guidance you can give.
