Do your doodles mean anything and do you doodle?

I took a 2 day training class for work the other day and noticed while I was listening to the instructor talk, I was doodling in my training manual… Drawing a lot of arrows, then circles and some faces… I started wondering if these are what i consistantly doodle the majority of the time that i’m spacing out… does it mean anything? I doodle fingers and hands too…

I doodle all the time. Like when I’m on the phone with someone… The entire post-it can be full of nothing but shapes, drawings…

What do you guys think? Is there some psychological about it?.. what do you doodle the most?
