1.  Make sure the reader can identify the focal character.  It's important for the reader to know where they stand.

2.  Establish short-ranged goals for the scene and keep that goal the center of attention.

3.  The main character must be strong.  This is the year 2017, readers do not like a wimpy hero or heroine.

4.  Create a sense of urgency.  This will force your characters to take immediate action.

5.  All opposition should be threatening.  Example:  Not spiders, but a man-eating tiger.

6.  Have strong villains.  A weak villain makes a weak scene.

7.  Each scene must count.  If your story moves forward without the scene, then delete the scene.  

8.  Don't make your scenes tedious.  Each scene should have a different goal, therefore, a different problem.    

9.  When writing your scene, go for the unexpected.  Make the reader wonder what the character will happen next.  

10.  Make sure your characters have a wide range of personalities.  This will keep them from being boring.  

11.  Give your hero or heroine lots of trouble.  To keep the reader turning the page, each scene should have potentially disastrous consequences for your character.

12.  Your disaster should be unanticipated, but logical and evolve from the materials in your story..
