Last summer vacation, I used to give advice of study to my younger sister. It was all about how to choose a proper major before going to the university. You know, my younger sister was about to become a college student. Before that, she was not pretty clear about the subjects, she has got no idea about the advantages and problems on each subject. I told her that two things are important. No.1, it has got to do something with her personal interest, or let us say, it is passion. Passion is the greatest love in the bottom of the heart, if you want to succeed someday in the future, you have to love what you do or study. No.2, location. My opinion is that those who want great future need to study in a super big city. By doing so, you would probably have the opportunities to become elites I could say. As is known to all, the better educational resources, good job opportunities or such. The two points that I have mentioned should be really vital. By the way, I remembered that it was a sunny afternoon when I gave her some sorts of advice, she told me what she thought about as well. After this conversation, I thought that she would probably think about it in general. That it is.
