is right. Being a digital nomad is totally possible but you need to accept that there are ways it works and ways it doesn't, and some ways are easier to make it work than others.
I am 22, Australian and currently working towards a 'nomad at will' lifestyle. I say 'nomad at will' because I don't want to only own what's in my backpack, living and working in random places all around the world; although I suppose that is the definition of digital nomad.
Basically, my ideal situation is to own a modest house - in any country - while having the option to travel and take my work with me. If I ever get bored of the travelling, I can always go back to my own home, a lot of travellers don't have that option.
I work in software development, that's basically the number 1 job people will tell you to get if you want to live that way. But I'm not only working in this field because it suits my ideal lifestyle, I'm also good at it, and I enjoy it, and I made some very valuable friends during my previous career in drafting (which helped me get the software job I have now). I think that's an important thing to remember, don't just say you're going to become a software developer because that's the best job for remote work, you should pick a job that you wouldn't mind doing even if you were working in an office.
Focus on becoming an expert. People pay for expertise and experience, and there are plenty of businesses that will gladly let you work from wherever you want as long as you're good enough at what you're doing and pulling your weight.
