Let me start out by making a bold statement: Any career can be a nomadic career.
It doesn’t matter what you do or what your skill set is, you can find a way to make money doing that from anywhere.
One of the ways I like to define a nomadic career is that it is something you can do to make big money while you are sitting on a beach somewhere.
Or anywhere you like. Like nomads and wayfarers everywhere, you can be location-independent and still make a respectable income.
It doesn’t matter what you do, if you think about it long enough and are creative and open-minded, you can find a way to make money doing what you do right now online.
