To get to the bathroom where I work I go down a hallway, turn left, the first door is the women’s bathroom and the second door I come to is the men’s. I do that same pattern many times a day. Go down the hallway, turn left and go in the second door. After working there for years it becomes an unconscious thing. Go down the hallway, turn left and go in the second door. I can keep my active mind on something more interesting. Go down the hallway, turn left and go in the second door. This becomes a problem when I approached this same destination from the opposite side of the building for the first time. Go down the hallway, turn right and go in the second door… wait…
