>>732178>Imagine thinking that it makes sense to learn Chinese to learn Japanese more easily.It doesn't make sense if you're not interested in Chinese in the first place, but it would make it easier (at least in some aspects).
>Do not learn Latin unless you have a profound interest in history and ancient texts.That's exactly why I'm interested in it. But I'm interested in Greek for the same reason, and that one has the benefit of not being dead.
I know how long it takes to really learn a language, I spent 2.5~4 hours a day for 2 years before passing the N1. And then I kept up that pace for another year before I felt that I had learned enough to be able to relax.
I understand and agree with your sentiments, though, and that's exactly why I mentioned above that I'm hesitant about starting another.
I believe that it's only possible to have a truly great grasp of a few languages. It's rare to meet someone "bi-lingual" who's equally competent in both of their tongues, and extremely rare to meet someone who has native-like ability in three languages. Your brain will just start letting go of whatever one you use the least, unless you actively work to maintain them all.
Sure, you can learn enough to get by in six or seven languages, but true mastery? No way.
I agree with you about "polyglots" by the way, their videos are much more impressive until you know a bit of any of the languages they "speak" and you realize they're stammering and fumbling their way through even the most basic interactions.
