Repetition is the key. It's very difficult, at first, to consistently throw a ball in the same way. It's also difficult to do it in the same way with both hands (right to left, left to right). Once you master the simple action of throwing the ball consistently from either hand, throwing 2, and then 3 balls at a time is much easier. When you can juggle you won't ever look at your hands, you just look at the space in front of your eyes and your hands will be where they need to be. I can juggle 3 balls quite well, but I can not for the life of me juggle 4 (different pattern) or 5 (same pattern as 3, more balls). 4 is extraordinarily difficult for me. I approach it by separately juggling 2 balls in each hand (no ball swaps hands), but my left hand betrays me!
