Do not put statements in the negative form.
And don’t start sentences with a conjunction.
If you reread your work, you will find on rereading that a
great deal of repetition can be avoided by rereading and editing.
Never use a long word when a diminutive one will do.
Unqualified superlatives are the worst of all.
De-accession euphemisms.
If any word is improper at the end of a sentence, a linking verb is.
Avoid trendy locutions that sound flaky.
Last, but not least, avoid cliches like the plague.

I love this rules. I have a big problem with starting my sentences in the negative form. In fact, my novel is pretty much mostly that. A lot of “glass is half-empty” characters. It’s been through critique partners and betas with no one pointing it out. More editing. Fun times, fun times…

Thanks much! I’m sure you will hit the perfect stride with your novel soon enough. If you ever need someone to give you feedback on your manuscript, I’m here!
Best,
Kim
Thanks for the offer. If you ever need someone to beta, let me know.
