That's a nice way to think about it. Looking back at the big "travelling phase" in my 30s, there were lots of years where I only grossed between $10,000 and $20,000 for the year. That was plenty, though, to spend most of the year living out of a backpack on some remote tropical beach. A lot of it actually ended up in savings.
That was contracting, so I needed to come back to LA to refill the travelling stack. It doesn't take much work to pivot that into a SaaS product or two that replaces the same amount of income. Again, maximising for free time and flexibility with profit being a nice side effect.
Then it gets really good.
