Author's Point

If you want to be a writer, the First thing you need to know is that

ORIGINALITY IS A MUST TO BE SUCCESSFUL

Second

ORIGINALITY NEVER COMES WITHOUT DEEP CONNECTION WITH YOUR CHARRACTERS

Saying that, another aspect comes - CHARRACTERS

Characters are the main drivers which moves your story and are the only way to connect to your audience. Hence, interesting characters with different shades are a must in every story.

Audience usually decide to go on with your story only in 1 and maximum 2 chapters. If your characters and story line is not fast and interesting enough to stop them from moving to another novel, then it's of no use.
