This requires me to look at every aspect of the world around me with a continuous questioning attitude. Why do we do it this way? How else might it be done?
Fiction writers aren't the only people who benefit from thinking that way. Those very questions have led to wonderful inventions like flush toilets, traffic signals, guacamole and the income tax.
As I tell my writing students, the first answer you come up with isn't necessarily the right answer, or even a good answer. You may not even be asking the right question.
