根据短文内容，完成下面的表格。
Dear David,
     I am very upset and I need some help. You know I will finish college soon, and I must decide
about my future. I am outgoing and good at speaking. I love to talk with others. So I want to be
a TV reporter.
     But everyone in my family has a different idea about my future. I don't know how to choose.
My father says I should go to England to study. My mother says I should be a doctor as she. And
my brother wants to start a computer company (公司) with me. My sister is a singer, so she asks
me to learn to sing from her. And my uncle works on a farm. He says I can work with him on his
farm.
     So, you know it is very difficult for me to decide which one is better.
     What do you think?
     Write to me soon. 
                                                                                                                                 Yours, 
                                                                                                                                Michael
