A writer is someone who can make a riddle out of an answer. ~Karl Kraus

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.
~William Safire, "Great Rules of Writing"

Books want to be born: I never make them. They come to me and insist on being written, and on being such and such. ~Samuel Butler

A metaphor is like a simile. ~Author Unknown

Proofread carefully to see if you any words out. ~Author Unknown
