Brave/Risk

It occurs to me, that while pitching a synopsis in class that the class wanted more outrageousness in my story.  I ponder this notion as I am like, wow, do I really want to take things to the nth degree (or near it)?  The concept is simple, but the execution requires a lot more finess, rethinking and re-writing.  Am I brave enough to push past my comfort zone?   I really am at the service of the story, and I would LOVE for the story to take on stronger, interesting elements.   It means going out on a limb, which bothers me a little, BUT it also excites me.
