This is a wonderful feeling.
I can't get enough of that feeling, and that's why I learn a language every two years.
So this is the whole polyglot secret.
Find effective methods which you can use systematically over the period of some time in a way which you enjoy, and this is how polyglots learn languages within months, not years.
Now, some of you may be thinking, "That's all very nice to enjoy language learning, but isn't the real secret that you polyglots are just super talented and most of us aren't?"
Well, there's one thing I haven't told you about Benny and Lucas.
Benny had 11 years of Irish Gaelic and five years of German at school.
He couldn't speak them at all when graduating.
Up to the age of 21, he thought he didn't have the language gene and he could not speak another language.
Then he started to look for his way of learning languages, which was speaking to native speakers and getting feedback from them, and today Benny can easily have a conversation in 10 languages.
