@MLClark I envision myself in an empty classroom, in front of an empty chalk (if you're old school) or white board. I draw a huge circle, slowly. I write the number 100 to fill the circle as possible, slowly. I retrace the outer circle. I slowly erase the number. I retrace the circle. I write "deeper" in the center of the circle. I retrace the circle, slowly. I decrement the number and write. And repeat. And repeat.
