See if you have good mind control over your body. This is left brain, right brain stuff.
This actually is true even though it may seem stupid and it's going to really frustrate you, but it's fun!
While sitting at your desk, lift your right foot off the floor and make clockwise circles.
Now, while doing this, draw the number "6" in the air with your right hand.
Your foot will change direction and there's nothing you can do about it.
See what I mean? So you don't have control then.
