Creativity
When people say to me that they aren't creative (etc.), I think it's more a case of mistaken perception. I bet, at least some of the time, it's the mistaken notion that they have to make something, or create a finished product. You don't. If you're just doing it for therapy or fun, all you need are materials, and to fiddle around. Squish the clay. Slop the paint around the canvas. Write out slews of words that have nothing to do with each other. Sometimes the benefit of the creative process, is in the process itself; not the finished object.
