So, after a year in Belgium, I came back to Finland. I started noticing certain things about the place that I had already gotten used to and don't really like, such as the amount of drunken teenagers on weekends, the fact that public transportatio, although good, is rather sparse (which is fine in summer, but in winter is no laughing matter) or the relative scepticism of most public officials. This all reminded me of when I arrived in Brussels, as I was not used to the dirt and the beggars in the streets. Don't get me talking about Mexico City, which is sadly renowned for its insecurity and pollution.
However, I remembered that it all depends on how much you make out of things yourself, and whether the pros outweigh the cons. There's always two sides of a story, and there is always something good that can be found. In Brussels it's multiculturality, in Helsinki it is nature and safety, in Mexico City its vibrance and cultural life, to give just a few strong points.
It's all a matter of making do with what is there, what you have and be determined to have a good time wherever you are.
I agree. Although, some places are much easier to exist in than others. Part of me would love to live in all 3 above mentioned places, for the exact reasons you mentioned, but I doubt I could do it for too long.
