What Are the Best Languages to Study?

The language that I find most useful traveling around the world is often German because the Germans are committed travelers. So then if you want to go further as English being your dominant, the final language is that you could discuss would be Latin and Greek. And so you could look at those classical languages. We're in a classical language phase in our family now. But with regards to Greek, then we get to the heritage languages or religious languages that are important to me.
