The correct answer is:
Writing is a personal process and there is not just one way to do it.
In the first chapter of On Writing Well, the writer William Zinsser recalls being invited to a school in Connecticut to speak about writing as a vocation. Mr. Brock, a surgeon who had started writing as a hobby, was there to speak about writing as an avocation. This allowed the students to have access to different perspectives on writing and to understand that there is not just one right way to write.
