Eliminate the justifiers. "She felt herself becoming dizzy," or "She grew dizzy?" The first sentence pulls away from the action, interposing perception; the second states the action, directly and succinctly, and makes room for the reader. More of the latter and less of the former makes a stronger story.
Justifiers situate the narrator between the reader and the story. Let them bow out graciously, but do eliminate them.
Rarely should a line of dialogue require an adjective. Convincing dialogue speaks for itself.
It's true: adjectives tend to drag. Prune them ruthlessly.
Needless repetition, needless to say, is your story's ticket to the abyss. It's a story killer, needless repetition, and that's all you need to say about it.
"She climbed the worn steps, gripping the sticky bannister and listening to the creaking wood beneath her feet, while eyeing the ominous shadows at the top of the staircase," or "She climbed the worn steps, eyeing the darkness at the top?"
Do not fear simplicity.
"Jane licked Joan's salty love pie," or "Jane licked Joan's aquatic folds and tasted the sea?" Hmm. Both at least refer to salt. The former might be praised for its pithiness (eh), and it pursues simplicity - but it's also opaque, and a tad crass. The latter trends artsy-fartsy, but it offers a suggestive image and invites the reader to associate with the story through sense memory (touch, the texture of aquatic folds, and taste, NaCl).
Moliere is reputed to have said that he knew when his work on a play was done, not when he had put everything into it, but when he could take nothing more away. Pursue simplicity. Stay honest.
Reread "Cooper's Literary Offenses," by Mark Twain. More importantly, reread his follow-up, "Fenimore Cooper's Further Literary Offenses: Cooper's Prose Style." A great lesson in writing.
Never publish a first draft of anything, ever.
Never publish a second draft either.
Strive to entertain.
And, finally, for now, a small prayer. O lord, for the sake of better writing everywhere, please smite the word smirk from erotica's vocabulary. Unless muttered by a character who is soon to die painfully, or used with utter objectivity, let it be wiped from every page. Thank you. Amen.
