What is voice? Is it really a thing? Does it really matter that much? It's one of those things that's never readily apparent in your writing unless it's nonexistent.
It's an age-old problem: How can I be original in a sea of content? How can I possibly create a new, fresh idea when all the good ideas seem to be taken? Or, worse yet: What can I do to prevent my original idea from appearing in some other story before I'm finished writing it?
