You can find Aunt Julie’s first five completely breakable rules of writing here. Rules #6-10 are here. Let’s waste no time moving right along to rules #11-15 (although they’re really more like gentle guidelines).
11. As Samuel Goldwyn said: “If you have a message, send a telegram.” Just tell a story—the thing you care about will magically emerge.
12. Never throw anything away; you never know when you might want to cannibalize yourself.
13. Avoid big chunks of anything, especially the parts that most people tend to skip. When it comes to description, get over yourself. Say a lot with a little.
14. Wear your heart on the page. You’ve heard it before, and I’ll say it again—make us laugh, make us cry. If your own story doesn’t make you cry at least once while you’re 
writing it, don’t even bother. It’ll probably make you laugh—most writers love their own jokes—but remember that you’ve got to make the rest of us laugh. If someone says your jokes aren’t working, believe them. As for making us cry, don’t be afraid of either melodrama or emotion. Put it out there. Pump it up. You can always scale back later.
15. Write with truth, authenticity and honesty. Although they sound the same, these are actually three different things. Truth means that your characters are believable and real and behave like human beings, not soldiers sent out to do the author’s bidding. Authenticity means you’re scrupulous about research and detail. And honesty means you never cheat the reader—you don’t cut corners, you refrain from verbal acrobatics that interest only you, and you don’t skimp on the elements of the story that are hard or boring for you. Usually that’s research or plot. Everybody thinks their characters are great and they write fabulous prose. If that’s the case with you, work on the rest of it.
