I do house sales to boomers in US and save everything, only started last year but now I have 5x the money I had previously and still was able to travel 6 months this year. thankfully the job is pretty seasonal, only really busy in summer and fall. I'm gearing up for another 6 or so months away now and will probably be able to work again when I come home and quickly recoup what I spent.
point is, get yourself something that's seasonal and high income. sales is this for me, but there are other options. Don't expect to make serious career progress, but that shit is meaningless even though it's what everyone obsessed about in the US.
you can also work a low income job for a few months and travel a long time on that money, just requires some sacrifices. sleeping on a beach instead of a beach hut, for example. Plenty of people have traveled the world for next to no money, and they get some of the best experiences out of it because they dont use money to buffer them from life's problems like most rich people in the world.
