How to Write
This is one of the reasons I HATE superfluous flashbacks. Yes, we can use flashbacks. They are a literary device, but like the prologue, they get botched more often than not.
Oh, but people want to know WHY my character is this way or does thus-and-such.
Here’s the thing, The Spawn wants cookie sprinkles for breakfast. Just because he WANTS something, doesn’t mean it’s the best thing for him. Don’t tell us WHY. Reveal pieces slowly, but once secrets are out? Tension dissipates. Tension is key to maintaining story momentum. We WANT to know WHY, but it might not be good for us.
The Force was more interesting before it was EXPLAINED.
