If I catch myself doing things unconsciously the same way time after time, like always doing the windshield first when I clean the car windows, I'll make an effort to break the pattern. Don't know why...I just do.
I also don't like seeing stuff on a shelf, in a cabinet, in a drawer, on a table, etc. in perfect alignment. If I see things too perfectly aligned, I'll move a few around just to mess it up a bit
