I remember going back and forth between the student center and the computer lab in college, in different buildings. I noticed that I took a different route in each direction... surely, not optimal. On my way to the student center, I'd leave the library by the nearest door. On my way from the student center, I'd enter the library by the nearest door. I figured that my brain was breaking it down into hierarchical steps: the computer center is inside the library, so the first step in getting to the computer center is entering the library, and I would do that by the nearest door, rather than choose a door close to the activities building.
