Oh thats a very good question mate,
Nowadays I am studying an electronical degree nontheless in a future I would like go to USA or Canada so I realized that I have to study english or french ,then in that i moment ,I put in google searcher :“what is the secret of polyglot people”,and I found out a video from steve kauufman with a girl ,and I dont believed all kinds of languages that spoke so eventually I saw a bunch of his videos and obviously I noticed about this website ,thus that`s all
