Everyone is a linguist. Everyone has their price.
When I was 17 I could only speak one language. Now I speak 9. I am convinced that most people can learn to speak many languages. We are all potential linguists.
I am astounded at how strongly people cling to the belief that they cannot learn. This belief then becomes a self-fulfilling prophesy.
I like to ask “if I gave you a million dollars to learn the language in 6 months, or if your life depended on it, do you think you could learn?” Then the answer is yes. I guess like in the story about the old man and the pretty young socialite at the cocktail party, everyone has their price.
