I've always considered myself creative, even though I don't consider myself an artist, per se. I spent a lot of my childhood creating worlds in my head, at the same time as I read countless creations of worlds done by many science fiction writers.
This summer, I became a world creator. I have created a new sci-fi universe, and finished a novel based in it. It was one of the most amazingly fun things I've done in a long time. I got to explore in depth a variety of issues that I think are important in the world, and have fun creating characters, plot, and new worlds.
