Writing a great story starts with writing a killer intro
The formal definition of an intro is a brief introductory passage.

If you are going to start writing, make sure it is a short intro. When readers see a headline they expect the writing below it to contain content which relates to that headline. There is only so much time a reader will spend with an intro about sports when the headline suggested the article was about vacations.

Ask yourself; is it short enough that a reader is not losing his patience before the writing returns to the topic at hand?
