I want you to envision this tale -
A man wakes up in the morning, puts on his slacks and polo while reading the paper. After a morning filled with getting the kids to school and getting to work he spends his day in a cubical, furiously typing out report after report. During the filing process, his computer suddenly pauses for a moment... and then continues to print.
Problem averted he quickly dashes off an e-mail to his boss before grabbing his jacket and stepping into the bright light of the afternoon. He finds his car where he left it and then heads home for an evening of his favorite sitcom before putting the children to bed.
Riveting isn't it?
When writing your story, make sure and push your main character to his/her limits... and beyond. The normal MC is remarkable, for a reason. Because of their ability to stand out, and thus be worthy of a special story, they can and should tolerate more. It brings life to the page.
If your MC is about to spend the rest of the day slugging it out the sucking mud of a swamp, why not make the swamp mud super hot to give him blisters?
MC about to have to battle it out with the evil mage? What if that evil mage's henchmen lands a grevious knife wound in the MC's side. Now he's got to worry about defeating the wizard before bleeds out.
Having our hero's overcome insurmountable obstacles is what makes them hero's. Imagine this fight -
Clark Kent is walking down the street when he see's two robbers breaking into a bank. He quickly dashes to a phone booth, changing into his superman costume and bursting forth faster than the eye can see. As he runs up to apprehend the villains, he see's the police on the scene. Apparently someone had tripped a silent alarm and the police were able to arrive on time.
Not nearly as interesting as someone hijacking a bus that can't go below 50mph, being driven by a guy who has a heart-attack, and finding the bus is actually careening towards a bridge that is under construction... and the cop that shows up on scene just happens to be dark/mysterious/and works out professional, and did I mention the girl who takes control is just naturally flustered?
Books are entertainment... since they are entertainment they should be entertaining, stretching the boundries of what if is always more interesting than 'wasn't it neat when...'.
Just my thoughts.
