heres what ive always done since I was a kid. imagine nyc sidewalks, with fairly large squares/rectangles. in my mind i draw diagonals from the 4 corners, and i also avoide stepping on those imaginary lines as well as the real cracks. i started doing this as a little kid, probably just ADD and needing something else to focus on while walking.

I've done the same thing since an early age. I concluded a few years back that it had something to do with wanting to find patterns and order in the world. I went a bit farther however in that I would draw these imaginary lines in other situations as well - like looking for patterns of alignment between tables and desks etc. in classrooms.
