Important rules, with thanks to my friends at Writers Alliance of Gainesville:

1.  Avoid Alliteration.  Always.

2.  Prepositions are not words to end sentences with.

3.  Avoid clichés like the plague.

4.  Comparisons are as bad as clichés.

5.  Be more or less specific.

6.  Writers should never generalize.

Seven:  Be consistent.

8.  Don’t be redundant; don’t use more words than necessary; it’s highly superfluous.

9.  Who needs rhetorical questions?

10. Exaggeration is a billion times worse than understatement.

Finally, when confronted by an upset grammar Nazi, always say softly, “Oh, there, their, they’re.”
