Did you ever notice that when you read a book, most of the time the main characters are in great health? No one is struggling to breathe through a cold or think through a migraine. Sure, you get the idiotic heroine who runs in high heels and twists her ankle, but you know as soon as she goes down either the monster is going to devour her or the romantic hero is going to rescue her. Either way, she's not dealing with pain.
But writing a character who's trying to overcome some health issue can add a very enriching layer to a scene. So for this week's exercise, write a scene in which your focal charater has to overcome or work through some temporary physical handicap in order to accomplish his/her scene goal. A headache at a charity funding meeting, broken toes at a dance competition final... be creative : )
Got it? Good! Get writing!!
p.s. No need for you to write a heroine who tries to post to her blog during a bout of stomach virus. I can tell you from first hand experience, it's just not possible and won't make for enjoyable fiction ; )
