10. Carrie by Stephen King
If it hadn't been for Stephen King's wife, Tabitha, the iconic image of a young girl in a prom dress covered in pig's blood would not exist. King received 30 rejections for his story of a tormented girl with telekinetic powers, and then he threw it in the trash. Tabitha fished it out. King sent his story around again and, eventually, Carrie was published. The novel became a classic in the horror genre and has enjoyed film and TV adaptations as well. Sometimes all it takes is a little encouragement from someone who believes in you.
