A writer friend of mine posted this in her blog talking about where her ideas come from. Friends ask me this all the time. I’ve found my hardest problem is coming up with the main premise, and that often, the main premise or tag line changes completely from what I originally thought.
Once the characters are there, they take on a life of their own. They can create all sorts of problems when they won’t cooperate with what I want them to do! Nonsense, you say, they are your creations. You try telling them that! If I attempt to go in a direction they’re not interested in, they will clam up and not feed my muse.
