My advice for aspiring writers is simple: WRITE!! So often we get started, run into difficulty and quit. If the story is in your mind, it will always seek a way out. Sit down, take a deep breath and let the words flow. When you enter the world of your own creation, the story will take over; be a spectator, write what you observe, what your characters say to one another, etc. Before you know it, there will be many pages of words that have materialized, and the really cool thing...its YOURS!
