I MUST SPEAKE ENGLISH EVERY TIME

I must speak English every time,because I want to be clever in English. English is not my language, but English is International language. As International language,English is spoken by all people in the world. Such as American peolple, Australian people, Japanese people and some of people in the world. I am a student in Idonesia, so I must not only speak in Indonesian language, but also in English language.
