When I was learning Spanish, I was bored with the text in the textbook.
I mean, who wants to read about Jose asking about the directions to the train station.
Right? I wanted to read "Harry Potter" instead, because that was my favorite book as a child, and I have read it many times.
So I got the Spanish translation of "Harry Potter" and started reading, and sure enough, I didn't understand almost anything at the beginning, but I kept on reading because I loved the book, and by the end of the book, I was able to follow it almost without any problems.
And the same thing happened when I was learning German.
I decided to watch "Friends," my favorite sitcom, in German, and again, at the beginning it was all just gibberish.
I didn't know where one word finished and another one started, but I kept on watching every day because it's "Friends."
I can watch it in any language. I love it so much.
And after the second or third season, seriously, the dialogue started to make sense.
I only realized this after meeting other polyglots.
