In still other cases, people can consult, teach, write about or otherwise temporarily convert a career from doing to teaching or helping.

And, of course, there's always the possibility of changing careers.

Many people say: What I do can't be done over the Internet or by phone. Dentists, building contractors, teachers, IT professionals and others believe they're chained to their current locations. However, many digital nomads have found temporary work in foreign countries doing the same job. Sometimes they make less money, sometimes more. (In general, the more desirable the location, the less money you'll make.)

The most common objections feel like showstoppers, when in fact they are merely expressions of preference.

For example, some people say they can't work abroad because they might make less than they make now. But that's an expression of preference: They prefer the security of a higher salary to the freedom of working abroad.
