Fern woke and sat up in bed; she stretched, she yawned. She checked the weather—damp again!— chose an outfit, and got dressed in her favorite blue shirt.
She wandered downstairs and wheedled some breakfast from her mother. "Say, Mother," she said, as they finished eating. "Where’s Poppa going with that axe?”
Sincere apologies to E. B. White! But this unfortunate opening—let’s say it’s from Charlotte's Web in the bizarro universe where Spock has a beard — while perfectly “correct” in a grammatical sense, commits an all-too-common faux pas. It wastes words and the reader’s precious attention by clearing its throat and taking a bunch of practice swings while the STORY is just sitting there on the table getting cold.
“Where’s Poppa going with that axe?” is where this story begins. There is no need to start sooner. We can assume Fern gets up in the morning and gets dressed before breakfast. None of that is storytelling; that's what she does every day.
First drafts tend to be laden with connective tissue, as we writers wander with imperfect clarity from scene to scene. You can leave most of that out.
TIP: Skip to the good stuff, not only at the beginning, but all the way through. Write the scenes that matter. They’ll be enough.
