Importance of Theme

Be themed. And by that, I mean choosing symbolism, archetypes, and personalities for stories. Get in the mood of your story. Every story is a new world, and to understand that world as a writer and a reader, one must grasp the mood with intensity.

What to Put on Paper

If there's a book you really want to read, but it hasn't been written yet, then you must write it.  
~Toni Morrison


Write what you want to read. Don't try hard to impress people. Imagine and know what you want to read, and put that on paper.
