A person juggling six or seven objects or balls could easily be envied by those of us who don't possess the same skill. The good news is that juggling is a special trick that can be learned through practice.
Do you recall that old saying, "You need to learn to walk before you can run"? Well, that's basically how it is with juggling.
Begin with the use of one ball. Picture an arched bridge in the distance and throw the ball from one hand to the other, lining it up with that imaginary bridge as accurately as possible.
Attempt the same thing but with two balls. This time, throw the second ball from one hand to the other in the opposite direction to the first ball - as soon as the first ball reaches the height of the arch of the bridge. Catch the first ball with the hand you used to throw the second ball, and vice versa.
Continue this cycle until you develop manual dexterity in your hands, and better hand-eye coordination.
Incorporate the use of the third ball. Begin with the use of two balls in one of your hands, and the third ball in the other hand. Use your left hand for the two balls if you are left-handed. Throw a ball from one hand to the other. Now throw the second ball from one hand to the other in the opposite direction to the first ball - as soon as the first ball reaches the height of the arch of the bridge.
This time, throw the third ball in the same way as the first ball, and catch the second ball with the same hand you threw the first ball. Practice. Practice. Practice. You won't become a circus performer overnight. Re-read these steps numerous times, if you must.
