I think of writing like I think of cooking: it's part science, part art. Both have some rules to follow in order to avoid disaster, but that doesn't mean you can't be creative with the basic ingredients.
Like cooking, you can follow a set recipe when you write, and what you turn out will probably be perfectly serviceable. However, people don't line up at popular restaurants for "serviceable," run-of-the-mill food. If you want to get attention, you need to put the same old components in a new and exciting, yet still palatably pleasing, way.
Are you confident enough in your cooking abilities to create a new dish?
Are you confident enough in your writing abilities to create a new message?
Sometimes, you need to call in an expert who's already experimented with the building blocks, whether you want to feed someone's stomach or someone's mind.
