1. You can revise a project forever. Don't fall into that trap. No one gets out with the same book, and you might learn more from writing several stories than turning story A into story B.
2. It's almost a contradiction of #1, but write the book of your heart and revise it to get the book that is a better story.
3. Write something that makes someone feel an emotion or link to your character. It isn't always easy. Want proof, try it. And if you prove me wrong and discover it's easy, I'm fine with that too. The world needs as many good stories as it can get.
4. Writers who write a lot don't always remember their stories or characters' names, but it's okay. They've documented them on the page. They can go back and look them up. But for that moment when they were writing, that character and story should have been as alive to them as anyone with a birth certificate.
5. Writing fiction is all about reality. Creating a world in the imagination. Your characters need body language, pauses, expressions and maybe a few aches and pains.
