As you have known - English is the most useful language that people should learn to get good at. First, English is an international language. Therefore, it helps to communicate with people from other countries easily. that's great experience if you have some foreign friends and understand about many different cultures in the world. Imagine that how amazing if you can travel wherever you want with English. Second, most of important documents were written by english. It means that this language is able to open your mind. you read famous original books, watch US-UK films without translation... so you can improve your knowledge effectively.  Last, a fluently spoken english candidate is always received high recommendation from employers. more working oppotunities are offered which require english skills. if you are master in english, you'll get a good job, earn a lot of money and get more promotion. I really think that english is a best choice to study.
