Everybody's got them. Everyone. And if you say you don't have any, you're either lying or a sociopath.
They're those voices in your head. The ones that talk shit about you to your face. They sound just like you (which is especially insidious for a voice actor). I've got'em. They're loud. They're persistent. Persuasive AF.
