I agree only like 20% with this. I’m an European who migrated for studies and work to 5 other European countries. It does help to learn the language but if you go to a big city or a university town, most people will speak English and you only need to learn the coffee place/restaurant/supermarket basics. It’s still a big decision and op shouldn’t do it on a whim

I see you are the kind of person to say “the best time to start learning is five years ago, so I won’t start now”

As Kendrick Lamar would say “it’s not enough”
