What's your writing mantra?

While I recover from the intensity of completing revisions on WHO WANTS TO MARRY A MILLIONAIRE? here's a gem from Larry Brooks at StoryFix.

What happens in the story is driven by what the characters are feeling, where more often it is the other way around.

I love finding snippets like this, snippets that make us think and look at our writing in a new and positive way.

Do you have a favourite writing snippet or mantra?
