Very true. I was born in Brazil and thus learned Portuguese as my first language. Then moved to the US when I was five. My parents sat me down in my grandparent's basement and taught me English, it had to be done quick as school was starting very soon. Many years later I would return to Brazil and spent three months there. Starting with crude vocabulary and building it up as I went, over hundreds of interactions. The best way to learn a language, is out of necessity. Whether it really does hinge on you being able to communicate with others or if self-imposed. I wish more people saw it as something that must be done. Unfortunately, Google Translate enables laziness.
