Juggling is about catching.
Juggling is about throwing. Well placed throws land where they are supposed to, making catching fairly automatic. If you throw with accuracy and leave your catching hand where it is, the ball will fall into it.
The magic in juggling isn’t the skill. It’s the suspense of an audience expecting a ball to be missed at any moment, while the juggler is calm, knowing that the ball won’t miss its target.
He is calm because he aimed his throws right.
Emergency Response is overrated compared to Pro-active measure
Welcome to 2018, and lots of accurate throws.
