"To me sketching is like a 'right brain' exercise. I read Daniel Pink's, 'A Whole New Mind' about the time I was becoming a good sketcher. He talks about drawing and doodling as workouts for your creativity.I could feel it happening as I became a stronger sketcher. Like I had been bit by a radioactive spider I could feel my powers growing! Not just for pretty picture making or even concept communication, but my 3D visualization and problem solving skills. So my ideas were better, and to that point I don't think we're in the business of just having ideas. We're in the business of realizing idea's in the real world. "
