The act of having character.
What kind of characters do you enjoy?
Some of the strongest characters out there are almost over-the-top. The traits they carry are emphasized. Not only has he been hurt in a relationship...He's been emotionally scarred. Not only is the stepmother the most hideous creature in the world (borrowing a storyline from the "Undead" series), she's actually bore the devil's child. (Read it. It's freakin' hilarious.)
Do you find that authors exaggerate their characters and the traits? Is that the sign of a good author? Or should there be a little more subtlety? When you write a character...do you make them larger-than-life? Bold and brassy? Or rather calmer? Do you flex with each book? And what do you like to read?
