As you prepare your article for publication, keep in mind that, like a storyteller, you must keep your audience interested in your story. Tell your reader why you are moving from one paragraph to the next, and explain connections between ideas. If your reader loses your chain of thought, they will likely stop reading.
In the beginning of your article, tell the reader--in a captivating way--what your article is all about. Be sure to place your article into a broader context. Remember, our audience is composed of informed, multidisciplinary students. Readers must first learn the context of your subject before they can understand how your work changes the field or affects their decision making process.
Anecdotes are entirely appropriate. They provide a human context to your scientific research or advice and they provide a vehicle that holds the reader's interest. Telling your reader why you chose to pursue a particular avenue of research, for instance, is entirely appropriate, as would be a description of why a given strategy has been successful for you in the past.
Above all, keep your focus throughout the article and make sure you keep the audience in mind when writing!
