Nuuu not rehash (though to be fair, if you look up Eliot's notes for the poem I'm analyzing above it reads like a freaking bibliography or all of the images/themes HE rehashed from other people's work haha) more just wheedling out the basic human themes that make the piece mentally 'work' in the same way as the thing you're trying to write. Break it down into its constituents and start building from there, and build something that is new and not a rehash but still has that thread of common human experience running through it.

Again, I am aware of how pretentious this all sounds. I'm not trying to be.
