Too Many Flashbacks

In recent workshops I’ve been seeing a lot of flashbacks in my submissions.  Nothing wrong with flashbacks but they have to be judiciously used, and typically only to illustrate a character’s history.  They should be short.  They have to be dramatized (shown, not told), and they have to contribute something to the forward movement of the narrative.  In other words, flashbacks are nothing more than spice to the meat of your story.  Too many flashbacks, too many long flashbacks, and too many appearing early on are signs that you’ve entered the story at the wrong time.
