I dropped Spanish which was the only language offered during my high school years. I regret it, and now I’m embarrassed to start learning as a uni-aged guy. I want to learn Mandarin because then I would know English and Mandarin which would cover like 50% of the populations speaking abilities.
Basically I just feel like a dumb American and being a Marxist I need to know another language.
Learning a language is hard, so I understand why you haven’t learnt a second one yet. But as a person who’s interested in languages I can give you some tips.
Practise daily, whether that is through online apps or study books, preferably both. Watch news broadcasts in the language you want to learn, and read the news as well. Practise speaking, and if you don’t have someone to practise with, practice with yourself. Watch TV shows in the language and try to build towards not needing subtitles anymore. Listen to music in the language and look up the lyrics.
