Respecting your character’s background
Your characters will evolve throughout the story or a series. They will naturally evolve and will become deep and complicated; their personalities will start showing more strength and charisma. If you are attuned to your characters you will respect their evolution in your writing. A character that was bubbly in the beginning of the story, but has gone through a lot of heartache and difficult situations as the story progresses should not be presented in the same way – the situations that you create for your characters will permeate their personalities and modus operandi. Ignoring that important part, will result in a lack of credibility and will make your writing appear fake. Readers interact and identify with your characters, they feel what the characters feel. If a reader does not “feel” a character, he/she may get discourage and stop reading or lose interest in the story.
By being true to your characters, you are engaging the readers and respecting them.
