Too many writers think that all you need to do is write well-but that's only part of what a good book is. Above all, a good book tells a good story. Focus on the story first. Ask yourself, 'Will other people find this story so interesting that they will tell others about it?' Remember: A bestselling book usually follows a simple rule, 'It's a wonderful story, wonderfully told'; not, 'It's a wonderfully told story.'
