Writing advice I'm now trying to follow:
Substitute "damn" every time you're inclined to write "very;" your editor will delete it and the writing will be just as it should be. -- Mark Twain
Writing advice I gleefully ignore:
It's often wise to cut down on verbs of being, replacing them (whenever possible) with action verbs; that'll make your writing punchier.
I loooooooooove the verb "to be". It's my favourite verb. I work those predicate nouns and adjectives as hard as I can. I like the flatness of it, the plainness.
What's your favourite writing advice? Or your favourite advice to ignore?
