Macro Planners have their houses largely built from day one, and so their obsession is internal—they’re forever moving the furniture. They’ll put a chair in the bedroom, the lounge, the kitchen and then back in the bedroom again. Micro Managers build a house floor by floor, discretely and in its entirety. Each floor needs to be sturdy and fully decorated with all the furniture in place before the next is built on top of it. There’s wallpaper in the hall even if the stairs lead nowhere at all.
