Try to ask questions that your reader may also be having, like you see here in this non-fiction piece. Use examples of real life instances to touch your readers. An example of this would be a story about a writer who never was a success until he or she learned the value of adding angle to an article. You might want to give examples of the writer's first attempts that were considered very boring and read like textbook or encyclopedia. You can use the name of famous people also to move your readers, connecting them with your message.
Many writers often start off with a question.
Other writers like to make a very bold statement, provoking the reader to think about the subject of the article. Some writers also like to begin with a quote. In this case, perhaps a quote from Longfellow or Poe about writing. End the same way as you began it. Think of the article as a funnel.
