What are the speakers mainly talking about?

M: Mom, I’ m a little worried about college. I just don’ t know what to study. I don’ t know what my major should be.
W: That can be a difficult decision, John.
M: How can I decide?
W: Well, I’d start with your interests. It will help you if you study something that you are interested in. What do you like to read and learn about or do?
M: I guess I like dancing and helping people. Those are my interests, I guess.
W: What do you mean by helping people?
M: If people have problems, I like to help solve them. Or if people are hurt, I like to try to do things that make them feel better.
W: It sounds like you might be interested in medicine, then.
M: Uh, I don’t know...
W: Another thing I think you should consider is the possible jobs you might get and how much money you want to make.
M: How do I figure that out?
W: You can research different jobs at the library, and there are reports and data on how well different jobs pay.
M: I want to have a well-paid job so that I can have the money to travel.
W: Well, there you go! Income is going to influence you most in your choice of major. There is one other thing you should consider, too.
M: What’s that?
W: You know... scholarships, the money given to you for college. You might want to pick a major that will allow you to get a special scholarship. I know you’ll make the right decision.
M: Thanks, Mom.
