I always said that I am spatially impaired, can't see in 3 dimensions. All of my design attempts have been disasters, I know good design when I see but I can't visualize it at all. I hate moving furniture. Interior design is excruciating torture to me. I can't organize physical objects to save my life, but I will slavishly follow written diagrams. Which fits with my visual score of zero.

Thanks for posting the link, it was fascinating.
