Why is English important to me ?

English is important to me because is the most popular language in the world, i want my future to be good so i want to study English and every time in Ho Chi Minh city there are some people from USA and they ask me something and i don't understand any thing they say. Study English is important for me, sometime i don't really understand so i just ask my teacher or check dictionary. So do you think English is important to you ???
