Doing it wrong for fun
With our minds wired for the correct way of doing things, doing it wrong is challenging and fun.
Ways to do this in the small: Opening doors or brushing teeth with the opposite hand. Changing the order of getting into the car, putting on the seatbelt, and starting it. Picking up and carrying a bag differently.
In the small and big: Finding the automatic ways that things are done, and messing with it.
