I would like to address several of your posts together, using my own experiences.
As a fellow Chinese who lived in Europe for a couple years and lived in several cities across Canada, each a couple years (so not 2 week travels):
1. It forced me to abandon my old friends and make new friends. Is this a good thing? not necessarily. An easy thing? absolutely not. A good thing? I think so. First of all, distance kills friendships. And I'm forced to make new friends when I feel lonely. When I have new friends, I learn about their cultures, about their hobbies. I spent 20+ years in China and never got drawn into bodybuilding, now I do it everyday because my new foreigner friends introduced me to it and it becomes an integrated part of my life and source of happyness. I still keep in touch with a few close close friends remotely, who lives all over the world now.
2. It forced me to do things I normally won't do/step out of my comfort zone. This is related to your comment:
>Which when I thought about it is super ridiculous, why can't I enjoy these things if I was going by myself??? Or put in another way, why can't we see our local city and people in our local community with the same freshness, open-ness and kindness as we'd if we were tourists or backpackers traveling in a distant land?
You certain can, but it's difficult. Human brain is designed to find patterns. We get used to things fast. There's no incentive for us to step out of our comfort zone in familiar environments. Once we know about a shortcut, we'll always take it. It's the not knowing of the shortcuts that forced me to be out of my comfort zone a lot (and back to 1, I wont force myself to make new friends if I dont have to). Things like, I public speak a lot more than before, I try actively making friends, and again I workout daily now.
3. By doing all 1 and 2, I gained new perspectives about myself. About what really makes me happy. If I didn't live abroad, I'll probably anchor my happiness a bit more on the traditional Chinese values such as having a big place in the tier 1 cities in China and having kid(s), and make sure the kid(s) excel in all the stuff, just like my high school classmates are doing right now. Now instead I saw so many different ways of living one's life. So many different ways of finding happyness, I incorpated those into how I define my happiness. I do things that truly make me happy rather than things my peers are doing. On the flip side, I dont give fucks to many things anymore, because I saw ppl who dont give fucks to those and they are fine. I wont know those people in my old city with my old circle, or at least not as many.
4. It satisfied my curiousity. You can know a lot about the world by means other than traveling and experiencing in person. But can you be sure the experience is the same? Different or not, I was curious to know.
5. Lastly, if I can change history about myself, I'd travel sooner in my life. This is probably related to 3. People say traveling broaden's one's perspectives. Concretely I think what that means is it makes you better at problem solving. With more perspectives, you either gain new approaches to solving problems, or some problems become too trivia you give little amount of fucks than you previously would, or some problems become irrelevant to you. One example I think is I'm not as easily influenced by commericals, marketing, or news as much. And many of those are intentionally stress inducing. When I see things that are utterly important in one culture are not important elsewhere, it helped me stop accepting messages that tell me what's important.
I dont have a foreigner partner btw lol.
