when he says you are already an author I think he means that you already wrote your own work It doesn’t matter if is it in an essay or just an email you already did your writing in your life before and that makes you some kind of author and that will help you think like a writer and that would make easier for student or any persons to write and read like a writer and that’s why I think he says that.  Something I wrote before is a story I’m trying to create as it fantasy fiction book I’m trying to write it about a lot of magical creatures and I wrote a lot of character descriptions for my book and I wrote a lot of essays.  Yes, that writing experience will help me in college because I’m already used to writing and that would make it a lot easier for me when I’m writing essays or any other kind of work that would give me less stress and that would make taking and understand and passing the class a lot easier for me and that would make enjoy writing more and enjoying the class and staying for case in class more.
