How Can English Help Me in My Future Occupation?

I have stadied English since I was 14 years old. Then, I attended English conversation school to improve my English skills. I stadied hard. I had a great English teacher, Daisuke. He understood every-single-my mind. And also, he always helped me outside of the classes. After I graduated from high school, he was transferred to another school. Then I thought, "I really want to be an English teacher like he did!" Actually I like playing with kids, so I want to teach them. This is my dream.
