There is thrill in story. Someone famous (I don't quite remember who... But they were famous) said the words, "Only begin, and the mind grows heated." It's true. Start a story, and suddenly, the floodgates open. All it takes is the courage to write down a name. And then there's a sentence connected to the name. Suddenly, a paragraph pops up. Pretty soon, you've got a book.
Start a story. It's thrilling.
