All I can guess is that when I write, I forget that it's not real. I'm living the story, and I think people can read that sincerity about the characters. They are real to me while I'm writing them, and I think that makes them real to the readers as well. ↗
That actually is one of my huge challenges right now because I write best at night, no question. I can focus. You know you're not getting any phone calls, I can shut everything down, and I'm just more creative at night. ↗
