"There are nine and sixty ways of constructing tribal lays,

And every single one of them is right."

(Rudyard Kipling).

I totally agree with everything you say here. I always tell novice writers to find the techniques that work for them. Regarding "Kill your darlings," I tend to think Faulkner meant nothing more than, "Be willing to cut whatever doesn't work, no matter how good it might be." Experienced writers often say they frequently cut their best lines. But they don't cut them because they are their best lines. They cut them because, no matter how good, they don't work in the context of the story they are writing. When they do work, certainly they won't cut them!
