Revising (from Damon Knight, Creating Short Fiction):
Put the story away after you finish the draft, so you can come back to it fresh.
Does it make sense and mean something? If not, decide whether to abandon or rewrite.
Does it hang together? Are there pieces missing, or unnecessary pieces?
Is the opening comprehensible? Does it convey information?
Have you answered who, where, what, when? Do you at least know why? Is the opening consistent with your answer? If not, rewrite.
Does the ending round it off and complete the pattern, show the story’s meaning, satisfy the reader, explain the mystery, solve the puzzle? If not, what have you left out of the early part of the story that would make an ending possible?
Are the characters believable, consistent? Have you used the best point of view, person and tense? If not, abandon or rewrite. [I’d suggest rewriting a fresh draft, not just changing the POV, person or tense in the same file. You’re bound to miss something.]
If all that is fine, make every word and phrase justify its use. Block out a few words at a time on screen or paper, with a mask if necessary.
Rearrange awkward sentences. Shorten. Clarify.
Correct viewpoint slips.
Read your dialog aloud. Can you distinguish dialog from narrative? Does it sound natural?
Kill cliches. Correct spelling and syntax.
Keep going until you can’t stand to look at it any more.
