I always thought that learning a foreign language would be for a useful purpose if you need to. You can learn english because it's the second world's spoken language, and you can use it in real life as well as on the internet. Why would I want to learn a language I will never use? Like japanese or korean for example? Also actually (or maybe I always was) too stupid to learn something that hard to master.
Personally I just think languages are fun and interesting to know more about, so that’s enough fuel for me.
I’d like to learn Korean, French, Japanese, Italian, Finnish and Latin just for fun, but it’s intimidating and I’m lazy so it takes a very long time.
I speak my native language (Swedish) and (I think?) fluent English, and enough Norwegian and German to get by if I were to go there as a tourist.
(This looks like I’m bragging because I can’t put my second paragraph above the quote, but I was just joining the conversation, sorry if it looked like I was bragging.)
