My plans were similar to the now popular (within a small but committed group of people) Financial Independence Retire Early (FIRE) movement. I was more focused on lifestyle and increasing my financial independence (as apposed to striving for complete financial independence in order to retire very early).
My thoughts were more along the line of being able to avoid a full time job and possibly do some consulting, run my own business (with a lifestyle goal rather than a make millions goal) and have investments that supplement that income. I also wanted to be able to have that possible from wherever I chose to live. Often you are quite limited on where you can live (especially cheaply) if you require a high paying job.
I also understood by living more frugally I gave myself lifestyle options. Living frugally allows you to save money. But it also lets you experience what living on less is like and you know if that is what you want. It is for me. I would much rather have freedom from having to earn a bunch of money to allow me to spend lots of money.
I think Financial Independence Retire Early (FIRE) concepts fit very well with a subset of digital nomads. Those focused on FIRE don’t have to be digital nomads (in fact a very small percentage is) and digital nomads don’t have to be concerned with FIRE (in fact, few are). But they are both, at the core, about putting your life first and not letting your life on the 9 to 5 job hamster wheel drive your major life decisions.
Combining FIRE and location independent work provides some valuable benefits. If you have some investments saved up that can be tapped as you travel that can meet some of your living costs, this aids on of the bigger challenges – how to earn money while you travel. And if you travel frugally you can reduce your costs (below what you speed where you used to live).
