Tidiness is something that happens when you have frontal brain damage. You get very tidy. Tidiness is symptomatic of brain damage. Creativity, on the other hand, is symptomatic of a fairly whole brain, and is usually a disordered affair. The tolerance for disorder is one of the very few healthy signs in life. If you can tolerate disorder, you are probably healthy. Creativity is seldom tidy.
