Rod Serling, creator of the The Twilight Zone, succinctly explains where ideas come from (via Brain Pickings):

Ideas come from the Earth. They come from every human experience that you’ve either witnessed or have heard about, translated into your brain in your own sense of dialogue, in your own language form. Ideas are born from what is smelled, heard, seen, experienced, felt, emotionalized. Ideas are probably in the air, like little tiny items of ozone.

Felt and emotionalized? Isn’t it sufficient to just say ‘felt’? Am I dick for nit-picking like that?
I’m sorry, but it’s like getting served a perfectly prepared filet mignon with a hair in it. Sure I’ll devour it, but I’ll always remember that hair.
