       Allow me to give you a little advice about writing stories. First, make your characters believable.

  Make sure that they do and talk just like real persons. In real life, everyone is unique. If all your

  characters speak the same way and do things in the same way, you'll lose your readers from the start.

       Once your readers believe in your characters, you must get them to care. Each reader must be able

  to know at least one character, to almost become that character in his or her mind.

       Now it's time to write your story. First, make a plan. Your readers are part of the story now; they are

   in your story.

       One last thing. Your story must touch the readers' emotions. If you can make them laugh and cry

  along with your characters, you will be a successful writer.
