Art and design
When I was in a Drawing I course, I looked at my paper too long. My professor taught me to look back and forth between the page and the subject every few seconds. They had me sketch different areas of the page and not focus on one spot. I would have to set down my graphite and step away from my work every few minutes. Then I would draw large areas standing up and sit back down for details. This forced me to see my drawing from a fresh perspective and to make adjustments as needed. The lesson: a good way to create something interesting is to pack a bunch of perspectives into one piece.
In order to make a product ergonomic, appropriately sized, idiot-proof, trendy and manufacturable, it’s imperative to get fresh perspectives.
