Languages. That would really impress people. It would be French (because so many people speak it), Spanish (for the same reason), Mandarin (because it's so hard to learn), Latin (because this always makes a person look smart), and German (because living in Germany would be cool for me).
Rich people are annoying.
Mandarin is not that hard to learn.
Spanish is the most spoken language in the world so you would be likeliest to get that.
Mandarin is the most spoken language in the world and it also ranked as th most difficult language to learn.
It's absolutely not the most difficult to learn, it's not even the most difficult one I've learned. Chinese grammar is relatively familiar. The only reason some people think it's hard is because it's lots of characters to learn, which is no more than memorization. Learning the tones isn't hard at all, it becomes routine after a little practice.
I would say Icelandic is the hardest language for English speakers AFAIK
It's not the characters (of which there are thousands of), it's the fact that it is tonal. There is a reason why Mandarin is consistently scored as the most difficult to learn. On top of learning the characters, you also need to learn the phonetic alphabet.
In my experience the tones become second nature after not too long. You stop thinking of them separately and they just become part of the word's sound. ---
