Answer:
Me: Sister, I don't believe it's a smart idea for you to leave college.
Sister: Why not? I've always wanted to be an actress and college sucks.
Me: Well, what if you don't get any roles? You would've have left college and not received a degree so you will find a hard time getting a job.
Sister: Well that is a good point but college is horrible.
Me: Maybe you don't need to be in this college. You could come home and do community college which is super flexible and you will also be able to pursue acting and also get a degree. Or maybe you could change your major so you can find a career that allows you to work in the acting field.
Sister: Hmmm like a director or a producer?
Me: Yeah! There are a bunch of directors that act in their own movies.
Sister: Thanks for telling me all this, I'm really considering your suggestions!
