9. Adverbs dilute.
10. Raise your effort. Lower your expectations.
11. Ignore discouragement. You'll never know real negativity until you tell people you are writing a novel. The last thing a human who spends their day selling home insurance in an office that smells of egg sandwiches and despair wants to hear is that their old school-friend is going to be an international bestselling author. So ignore them. All of them. Well, except that latter-day Malcolm Bradbury, Katy Perry: 'Make 'em go, oh, oh, oh/ As you shoot across the sky.'
Just one rule: write! Every day.
That said, these 25 rules will get you into the right frame of mind.
