As author, your job is to share your knowledge and stories with readers. As editor, my job is to help you organize your thoughts and share your knowledge and stories in a readable, enjoyable way. During the work, I may poke at your assumptions to see if they're strong. I may question your statements. I may suggest adding or eliminating content. Depending on the piece and its purpose, I may also suggest adding graphics or images, or weaving a theme throughout. In all cases though, know that I act as your partner and advocate for your readers to create a piece you'll be proud of.
