This problem existed long before digital nomads. My father was in the diplomatic corps and we lived overseas a few times as a child into my early twenties. I went to college in Germany but it had to end when I became an adult and moved back to DC. It took me decades to readjust to life in the USA. Then I got married and kids and all that. Soon you’ll forget about traveling so much. Finding a place to do that is the hardest part.
