I'm curious how you make it work. Any tips? What are the drawbacks? Do you ever get tired and just want to have a place to call home for a while?
I'm not sure everything is so black and white, either/or.
Being a digital nomad doesn't mean you have to be on the road all the time. It just means that you can, if you want to! Being a digital nomad is all about flexibility and living the life you want, not the one you're "supposed" or "expected" to. The definition of life on the road is different for everyone. Paul and I often rent an AirBnB apartment in some nice place with great WiFi, like Medellin or Quito, and stay for a few weeks to rest up or get work done. Then, hit the remote Andean tracks again. One might say, we're not on a "true adventure" if we hang out at leisurely AirBnB apartments once in a while, but the beautiful thing is, we don't really care whether our trip is kosher or not by some made up standards. We love what we do and how we do it, and that's all there is to it.
Some people might want to wild camp and only ride gnarly off road tracks all the time, some might want a lot more comfort and luxury - but there is no right or wrong way to travel, and there is no right or wrong way to be a digital nomad. It's all about freedom!
So if you want to do it month on, month off, or three months off/on, or in whatever other way you think you prefer, then that's the perfect way to do it.
It's the same with "it's either expensive or uncomfortable". Not necessarily. A nice, comfy two bedroom apartment in Medellin's fancy El Poblado area costs $17 a night, which isn't that much. And sure, Paul and I have slept in some very basic, cockroach-infested hostels and wild-camped a lot, but that's because we try to get to very remote places. Again all of these are just personal preferences. Leveraging world's currencies, you can travel very comfortably for $50 a day or less including transport, food, and accommodation. That's $1,500 a month or less, whether you're hanging out at the turquoise blue beaches of the Caribbean or going out for drinks in Buenos Aires.
Tips? Do what you love! In our culture, work is virtue, and the harder the work, the higher the virtue... and I think we got it all wrong. I'm never more productive and creative than when I'm doing what I truly love. And when I have to force myself to do something, the outcome is never great. I't okay, or it's mediocre at best... But when I'm in my element, awesome things happen.
And no, I don't ever get tired. As I said, we do stop for longer periods of time sometimes. The world is home at this point. You stay somewhere, the old lady who sell avocados around the corner starts putting two aside for you every Wednesday, the supermarket security guy starts saying hello, the shopkeeper knows you want your water from the back of the fridge... Everywhere is home:)
What I do miss - badly sometimes - is my own language. But then, there's always Skype. And if I get homesick, a round trip plane ticket to Europe is around $400 so I can get home once in a year or two if I really want to.
