Keeping a daily sketchbook tends to reveal the patterns of your life. I would often draw during lunch breaks from work at a local bar called JD'S that has since been closed down by the health department (a bad lunch choice by all accounts). Over the course of a couple of years, I did the same drawing on at least three occasions. This guy sat in the same position with his arms folded in the same way on each of those occasions, but I didn't notice until I was going though my old sketchbooks.
