There are many challenges in learning any language, sometimes it's social or it's lack of information about that particular language and for someone it's their confidence, loyalty, hardwork, dignity and consistency towards learning or practicing it. Currently i am learning English as it is not may home or native language but still we Indian's are learning it because it will help us to become more successful in our professional life's. For someone it could be their interest, hobby, need and may be they are learning to show off.
