Don’t be afraid of violent tectonic events. The world is not shrinking in the sense of collapsing in on itself the way a black hole would. Statements like “the world is shrinking” are only in reference to how it is becoming more and more easy to do things which only a few years ago would have given people rightful cause to laugh in your face at the absurdity of such a thought. The fact that a country of significant size exists only online (in a video game, no less) is just one aspect of how the world has gotten dramatically smaller within a fairly short period of time. And as well, the fact that education is no longer bound by national borders is another dramatic change.
You are most likely old enough to remember when it was a big deal to travel a few hundred miles to another part of the state or country, in order to receive a good education. But in this day and age, you may not have to do any kind of traveling at all, even if your best educational opportunities lie on the other side of the world. Nowadays, you may have online options which can blow anything local (or even national) out of the water. And of course, you may also decide that traveling most of the way around the world is beneficial to you, too.
The important thing about your education may not so much be in where you receive it, but what you receive when you get there. If the best medical school is in one country and you want to be a doctor, that would be the best place to learn your profession. If you want to learn architecture and the best teachers are in Florence, Italy, that is where you should go. The world is no longer bound by xenophobia or by national boundaries. We’re at peace, and it’s time we started using that fact.
