I'd like to suggest something a little different. You say you'd like to go somewhere to make money for traveling, but if it were me I would consider my work location a form of travel itself. So why go to, for example, Korea - a place that might not be particularly appealing culturally, but where you can make good money... so that then you can travel in, say, Indonesia or Vietnam, the places you'd actually like to see? And then, as you are passing through rural villages in Indonesia or whatever, you'll be saying "Wow, what a fascinating place, I wish I could stay."
If I were you, I'd consider not where the best money is, but where you'd actually like to be. Working in a foreign location for an extended time is such a more meaningful experience that passing through as a tourist.
I'd take a poorly paid job in a small town in Vietnam over a well-paid gig in Seoul anytime. Consider it!
