One thing that can trip up even experienced writers is giving everything away in the story too quickly.
It’s always a temptation for me. I tend to want to reveal things too quickly in my story. I want to explain everything as it happens so that readers won’t be confused.
But when I reveal too much, I end up halfway through the story without enough material to make a full-length novel.
Areas where it may help to raise questions:
Questions about character behavior. Sometimes character motivation isn’t clear. But as long as that character is behaving consistently, readers will want to learn why the character is acting that way.
