When I write, I tend to write in a specific format.  I am most comfortable writing in the form of a script, most commonly for theatre.  This allows me to write a lot  of dialogue to tell a story (which the theatrical form demands), and something that I think I’m pretty good at.
I’ve decided, recently to try my hand at another format: the novel.
I’m going to do NanoWriMo this year, and am working on the process of outlining the story.
I’m told that stepping out of the comfort zone can be good for creativity, so we’ll see what happens.
