In creative non-fiction you write what you know. You can't make it up as you go along or pretend something really happened. Or pretend something didn't. It's like pouring out your heart and soul into this paper on a screen that's going to be up for scrutiny and ridicule. But they want to be entertained too. It's not enough for it to be real and honest, it has to "catch the reader's attention" and "make them want to keep reading." So not only can they tell you that your writing is shit, but that your life is shit and it doesn't speak to them.
So how do I speak to you?
