But my number two piece of advice is this: be deliberate.

Honestly this would fix so many pieces of bad writing advice. Don't forbid people from doing something, tell them to be conscious and deliberate about it. This could help stop people from falling into common mistakes without limiting their creativity. Black and white imperatives may stop a few annoying beginner habits, but ultimately they will restrict artistic expression.

Instead of "don't use epithets": "Know the effect epithets have and be deliberate about using them." Because yes, beginners often misuse them, but they can be useful when a character's name isn't known or when you want to reduce them to a particular trait they have.

Instead of "don't use 'said'" or "just use 'said'": "Be deliberate about your use of dialogue tags." Because sometimes you'll want "said" which fades into the background nicely, but sometimes you will need a more descriptive alternative to convey what a character is doing.

Instead of "don't use passive voice": "Be deliberate about when you use passive voice." Because using it when it's not needed can detract from your writing, but sometimes it can be useful to change the emphasis of a sentence or to portray a particular state of mind.

Instead of blindly following or ignorantly neglecting the rules of writing, familiarize yourself with them and their consequences so you can choose when and if breaking them would serve what you're trying to get across.

Your writing is yours. Take control of it.
