There are several really good things about being a writer. First is the excitement and thrill that comes with the creative process. When the writing is really going well, it creates an incredible high - or maybe it's the wine. I don't know.
Seriously, it is the writing. I can't drink wine and work. Wine makes me too sleepy.
The other best thing about being a writer is connecting to readers through the stories and the people in the stories. As a reader, I often find characters in the stories I read becoming like good friends that I am eager to meet again. And as a writer, I find that the characters I create start living in my head and in my house.
