Don’t believe everything you hear.
Personally I’ve been starting to learn languages simple for enjoyment and out of curiousity. I neither need it for private nor business reasons. Although it is helpful to at least have a basic understanding of a language and the culture of those who speak it when watching series and movies from that very country with subtitles. There are just so many nuances that get lost in translation. And beeing able to understand English has proven very useful, too. So maybe one day what I’ve learned will have an unforseen benefit.
However, my experience is that the most joy comes from the things that are the most useless.
