Digital nomads are people who use telecommunications technologies to earn a living and conduct their life in a nomadic manner. Such workers often work remotely from foreign countries, coffee shops, public libraries, co-working spaces, or recreational vehicles. It is often accomplished through the use of devices that have wireless Internet capabilities such as smartphones or mobile hotspots. Successful digital nomads typically have a financial cushion or need to develop high levels of self-reliance and self-discipline.
