For the Reddit users on this board who come from a country where English is not the primary language, or whose first language was not English, I am curious to know: How did you learn English so well?

Having grown up with Mexican heritage, I was fortunate enough to speak both English and Spanish fluently, as both of my parents primarily used both languages, despite their fluency in English. It was quite natural for me to speak both languages during my childhood and now. Interestingly, my parents' experiences differed, as they primarily spoke Spanish at home and English outside during their own childhoods.
