Why do I choose my major ?

My major is mechanical engineering. When I was in my junior high school, I found that my English skills are a little poor. So, I choose the engineering majors instead of business majors. In these days, I find that there is an important reason for me to choose my major. This is because my grades are not enough well to study in electrical engineering, and I have to choose mechanical engineering to study finally. I have learned it for seven years, I think that I do not have any interests in it, and I have more interests in computer science engineering. I have ever considered transfered my major at first, but it is very difficult to me, and I have to learn it again. Thereforce, I decide to continue studying mechanical engineering. In conclusion, if I were in my junior high school, I will formulate it very seriously.
