Read your post and found it great. Being a digital nomad does mean being able to work on the fly anywhere. I became a freelance writer and netted a contract with a US firm online that I wrote SEO content for over 5 years.
Freelancing is a great way to go and I used my experience to create a massive package which includes wealth creation based on freelancing and writing. This is not an ad but you can take a look if you like http://mybucketwishes.com/library/
I have made enough money to do quite a bit of travelling and just take my laptop along earning money freelancing along the way. Travel be productive and enjoy life visiting the world.
