Learn to juggle.

Even if you seriously doubt your hand-eye coordination, juggling is probably within reach.

The easiest way to get the hang of it within a week is to start with two balls. Practice tossing just two up in the air, first with your right hand and then with your left. Work your way up to tossing a third when the first is at its peak.

Soon you'll be able to put separate tosses into one fluid juggling motion.
