This is how "I write what I know".
Not the literal/physical world, but the emotional, psychological, experiential human reality that is my own. That's what I know.
Once, I had bombed so badly on stage, I had to write it all out to vent on the page and recenter myself, or I would've spent a fortune in therapy. Not long after that I met a publisher who was ready to publish a short-story anthology connected to stage fright. One spot had opened up because a famous actress (can't name name, but think big) decided to withdraw her story, last minute. I pitched him and now my story, "The Little Old Lady", is in "Frightful Stages", Haworth Press (http://www.amazon.com/Frightful-Stages-Therapeutic-Robert-Marchesani/dp/0789013657/ref=sr_1_1?ie=UTF8&s=books&qid=1238200272&sr=8-1).
