I’m really glad to know that you are fond of reading and want to be a writer. It is necessary to read a lot if you want to write something. You need a lot of information for writing something. So, first of all, enhance your reading level and get more and more knowledge so that you don’t need to worry while need information for writing any article, story etc.  And take first step by writing short stories, but do get it checked by any elder at home. Keep this point in your mind that, it is not necessary that your first story is the best story, but a constant practice will lead you towards success.
