New input case for you: Person1: How long will it take to learn English ? Will I be able to take other courses next semester or will English take up all of my time ?
Person2:It ' s hard to say . Language isn ' t like other studies .
Person1: You mean I could finish this course and still not know English ? You ' Ve got to be kidding !
Person2:I ' m not kidding . Learning a language is a question of forming language habits and that takes time .
Person1: So do we have to stay in this English class forever ?
Person2:No . You just have to stay here long enough to get some orientation . Then you go on practicing and learning outside . A lot of learning depends on your personal motivation .
Person1: So it ' s really the same story . Practice , practice , practice and more practice is the only way to learn a language .
Person2:You said it .

informal
