Your opening is an introduction to who you are as a writer. The first 100 words are precious real estate that set the tone for the rest of the story. Reader engagement is critical and here is the quickest pathway to achieve that goal.
RIGHT FROM THE START
Story beginnings have to accomplish several goals. When in doubt, remember that information is far more important to the audience than action. Readers need to know a character’s sex, age, occupation, handicaps, and reason for being this story’s protagonist. Setting is needed for the sake of orienting a reader to the surroundings and time period. There also should be a suggestion of what the overall problem is in the story. All of these things don’t need to be explained fully, but there should be a sense of understanding.
Readers want to feel swept away into a story and this is one of the simplest ways to do it. I am a visual person and force myself to use auditory, tactile, and olfactory details. Use as many of the senses as are fitting to the scene.
Strong nouns and verbs are better than a dozen adjectives and adverbs. This is a standing piece of advice, but it is even more important when working within the first 100 words. A “construction worker” brings more of an image to mind than a “man” does. When that worker steps into a kitchen, a far clearer picture is made than when a man walks into a room.
Readers don’t always judge a book by its cover, but most will judge a story by its first 100 words.
