Brushing my teeth with my non-dominant hand

This is from an article about willpower:

"Just like practicing self-control in one aspect of your day (resisting a brownie, say) depletes the entire well, it also strengthens the entire muscle. “If I'm practicing self control in any domain, it should help me in all the others,” says DeWall. Multiple studies have illustrated that when you exercise self-control in one area of your life -- such as brushing your teeth with your non-dominant hand -- you can exert more willpower in another area, such as suppressing aggressive behavior. The two behaviors may be very different, but they share a common energy source."

For some reason, the thing that I got out of this is:

I want to brush my teeth with my left hand. That's it. Hahahaha

Hey, if it helps me learn to exert more willpower, why not? :D
