Sometimes, finding the right character for your viewpoint is difficult. If their outlook is too limited, your reader loses interest, yet if they are too wise, the reader feels left out of the discovery process. Your main character should be intricately involved with the story but with flaws that skews their judgment or pasts that color thier viewpoint. No one wants a perfect character.
MY characters have the bad habit of growing as I write. Suddenly, he or she does not fit the mold with which I began. This can be a good thing. Your character’s growth dictates the story arc. This allows for a tighter, more believable story line and fresher characters.
I’ve had characters destined for the Grim Reaper win a reprieve with their actions. It is so much more difficult to kill an interesting character.
