More random thoughts to add...
Back during the "genre" quarter, one of the topics was "Comedy". I struggled for an eternity trying to think of something, but was at a loss. As I was laying in bed, praying, I finally said, "God, I'll write about the first thing you put in my mind." Immediately, I heard, "Noah."
I said, "Seriously, God? Noah? How is that funny?" Of course God didn't answer - he's not in the kidding around business when it comes to prayer answers.
The next day after work, I opened a new Word doc and started writing. Who knew the story of Noah's Ark could be funny? It didn't win, but I was pleased with it, seeing as how I don't really do comedy.
More than once, I've given up trying to come up with an idea and just say a prayer and start typing, not having a clue what I'm going to write about. That seems to work pretty well. I've won 3 of my EC's with this method.
