Creativity is often perceived to be the domain of those who accept no limits, who attack the canvas unfettered, who pound out page after page in an unbridled response to the inner muse. But perception is not reality. Creative solutions are most often found within the boundaries of very real constraints. In the real world these constraints are the fuel that drives our creative engine. Without them we wander aimlessly. With them we focus energy and come up with astounding solutions, designs and insights.
