Who can I interview and where can I find information?

I would interview my sister because she went and finished college in four long years but that actually helped me be independent for awhile. I would also interview my brother because he is going to college in four years and will be in college for four years. I would also interview him because he is on the debate team and he debates really well. His agruments are so supportive. So i think that if I interview him he would give some good information to bring back from his debate team and he would be able to support it with very good details. Those are the people that I would interview.
