Have a 'left-handed' day (or right-handed if you're a lefty).

Force your brain to rewire itself by doing everything with your non-dominant hand for an entire day - from brushing teeth and eating to writing and using your phone. You'll discover how much you take basic motor skills for granted as simple tasks become frustratingly difficult. The experience gives you genuine empathy for people relearning skills after injuries and might even improve your overall dexterity.
