Traveling definitely broadens your horizons and I think it's crucial in becoming a truly open minded individual. It's a progression of sorts in the leaps you take - at first you'll maybe go on a trip for a few weeks, maybe then you'll travel for months, maybe do a round the world trip, then eventually end up living abroad. In the shorter stints, after time, it definitely feels a bit superficial and "vacation-ey" to me no matter what I'm doing since I've traveled so much. With age I think you sort of figure out your daily routine and with any free day you have, no matter where, you tend to gravitate towards some similar pattern just in a new country which even so accounts for something. I think about how a lot of people on these 2/3 week shabangs just want to get drunk, have sex, and still leave ignorant to a lot of things in regards to the country they've just visited.
I've lived in the States, Poland, Serbia, and Australia but spent heaps of time in Bangkok. After leaving the States and living in other places now even if I go from LA to NYC it doesn't even feel like a vacation - I've got to go to a new country for it to feel authentic. I've traveled to almost every state in the U.S., almost every country in Europe, India, Southeast Asia, and Australia. Poland was the best for me - the culture and history is one I could go on about all day, Polish is perhaps my favorite language, and within all of Europe the beer, bread, wine, cafes, etc... is just my preferred culture. I've also thought about these people who just want to get laid by Polish,German, Brazilian, etc... girls from whatever country, is that if you really know what you're into that you should just go rent a flat there for a month. Those things work out a lot better if you actually have a base, can make friends, and form meaningful relationships (albeit maybe short term) vs raging it for a couple of days. You'll experience a lot more as well.
I thought about teaching English in Asia but man... I'm just not into Asian girls at all. The culture's an interesting one and I'd definitely live there but it's sort of like when you go to a cool city but don't see yourself actually living there unless you got a really good job offer in which case you'd be all about it. I haven't been to Japan though - really want to.
