How can i fix this paper?

You repeat yourself about Jason using Medea without giving any more info. Also you say that you have used women for your own purposes but then go on to say you are still better than Jason. Really? You need to 'set up' the story and characters a little more. You talk about them like we already know them. Add a little background info. Who is Medea? and why is he/she to blame for Jason's shortcomings?
