I'm a graduate student, and am fortunate enough to have an office with a tall ceiling (~14 ft). I find it's good for theorizing and thinking through ideas of how to solve problems. However, when I want to get some work done that I know how to do, I tuck myself away in a corner of the library in between two aisles of books. With 8ft. ceilings and the books pressing in around me, I can be quite productive for ~2 hours, but then need to walk outside/ get up and move in order to keep working beyond that. Also, I read recently that red is good for focusing and being methodical, and blue for "thinking outside the box". I'm tempted to set up a room where one side of the room is red, and the other blue. Depending on what kind of work I'm doing, I could face one wall or the other.
