In the “global world,” knowledge of a foreign language(s) might make the difference between life and death.
There are some good ideas that might work for you.
I became (more or less) fluent in Hebrew in four months by following the classic language learning method.
Learn a new alphabet.
Learn basic pronunciation in basic sentences.
Slowly progress into longer sentences.
And a lot of input. Don’t worry about output (which is speaking and writing).
If you know 1,000 basic words, you can master 98% of the communication, like the speaker says. So why mess with mixing with total strangers, which can be quite stressful. I’d rather stay home and use dictionaries.
