I hear that 5 o'clock whistle in my mind like Fred Flintstone and I have to stop. I'm also not much of a morning writer. I have a sweet spot from about 11am to 4pm. But I really work during that time.
I have my ethics and morals. I have my anchor point of what is right and wrong in real life but I'm not afraid to entertain any and every aspect of personality in relationship to creating a character.
