I agree completely. When I was in Art school I was working on a project that instead of using charcoal to create the darks on a white sheet of paper, the assignment was to use a white conte crayon to denote the light areas on a black sheet of paper. I had taken my assignment home and was working on it in my living room when a neighbor and friend of mine knocked on my door and he came in and looked at what I was doing. He was a Mech. E student, and a damn smart person. He told me to my face that he could never do what I was doing because he wasn't creative.

"Creative" doesn't just apply to visual arts - it's a thinking style. And every human, ever, is creative - just in different avenues. And those avenues are all obtainable by all people.
