Beginning writers often look to other successful stories to learn how things ought to work. But so do all the other beginning writers. A book editor, agent, or script reader sees hundreds of manuscripts every year, all made up of the same pieces and hitting the same marks. You'll never get noticed in that crowd. If you want your work to be discovered, break format, shake it up, do something different. Make your sheriff 8 years old, make your two lovers twins, set your gothic romance underwater. You'll never be noticed if you don't stand out.
