I had a Russian professor who crossed the Iron Curtain to get here. In one aside to the class he said it’s extremely important to be able to think of more than one thing at a time. Fixation on a single idea can consume you and lead you into terrible choices you would have known not to make. He said this obsessed, possessed thinking pulled Russians along the path of creating the Soviet Union, and helped the Soviet Union kill tens of millions. I have seen what he meant happen for myself, many times now. I wish people higher dimension to their thoughts now, too.
