First and foremost, I would like to see your work for myself and get an idea of what kind of subjects you wish to work on; once there, I'd like to discuss ideas before getting to the actual writing. A teenager goes through several different things, so of course it's a broad subject, which is why I believe that pointing out the specifics for your intended articles should be one of the main priorities. Also, as I'm currently a college student, I do find myself around teenagers on a regular basis, which provides with an alternative insight on their issues.
