I like to remind people that creativity also isn't a spark; it's a slog. Every artist, inventor, designer, writer, or other creative in the world will talk about his work being an iterative experience. He'll start with one idea, shape it, move it, combine it, break it, begin anew, discover something within himself, see a new vision, go at it again, test it, share it, fix it, break it, hone it, hone it, hone it, hone it. This might sound like common sense, but it's not common practice, and that's why so many people are terribly uncreative - they're not willing to do the work required to create something that's beautiful, useful, desirable, celebrated. No masterpiece was shaped or written in a day. It's a long slog to get something right. This knowledge and willingness to iterate is what makes the world's most creative people so creative (and successful).
