Writing a seminar on Courage? Help please?

I'm writing my seminar on courage and I'm going to be talking about how my aunt with cf has been courageous with her disease, and also connecting it to a book I read, and to the book To Kill a Mockingbird because its one of the requirements for the seminar. It has to be 12 minutes long and I'm trying to gather more ideas about what to talk about and how to start it?
