I have studied and worked abroad and made some incredibly valuable connections. If you are interested in working internationally or even just having a couch to stay on in a country that you love, never underestimate the value of networking wherever you go.
One thing I have learned in my time abroad is that people are generally very friendly and love to talk about their home and culture. This is not always the case, but more than often it is. Making friendships abroad can make this big world seem a little smaller and help you feel more connected wherever you go.
The best advice I can give is to meet as many people on your travels as you can. It will definitely make your time abroad more enjoyable since the locals know best! Plus you never know when these connections will come in handy in the future whether visiting each other for fun or otherwise.
