The biggest concerns people have about life as a traveling digital nomad are financial: How do I make a living? Can I afford it?

Those are impossible questions to answer specifically. Only you know your career, circumstances and skills. However, it is possible to generalize.

Telecommuters can often work from anywhere there's an Internet connection. If you can work from home, you can work from Rome.

In many cases, people can do exactly what they're doing now, either for the same company, or another company that will let them do it from abroad -- or a foreign company where you would work locally.
