What should I write my book about?

Ok, I am really good at action, futuristic stories, and romance (and possibly some old-fashioned detective stories and sci-fi). And I write my stories from girl's point of view ... either that or the narrator's. so which should I do?
The before the slash is the point of view, the after the slash is the type of story. You can comment and tell me what you think the main character's name should be. PLEASE COMMENT!
