Avoid author inteuduction, they are anoying and a waste of time.
Dont make a cc only chapter
What is your plot where do it start,
Example if its about a Girl getting kidnaped, no one Care to see her wake up get dresses go to School, and then get kidnaped on her Way home
No just skip to her on the Way home getting kidnaped.
avoid Info dump , information shall be sewn into the story in a simple Way, not dump onto the readers at once
