Learning 5 languages at once
I won't say that all these languages have, I have learned. I am currently learning how to learn all 5. Sometimes you get mixed up, especially between dutch and German. But at least I'm learning more :3 I don't recommend you doing this, but if you like a challenge, you should! I heard that learning more languages can highen your IQ points, so if you're doing the same thing as me, keep going!
