Look at the ball, do not look at the other side.... just look at the ball...
Be careful not too focus on looking and end up getting hit by the ball
Just kidding. My lesson on volleying is hitting volley with my partner and do not let the ball hit the ground. Overtime improve the feel first and then slowly u will not need to worry where your hand, and focusing on the ball.
My coach always told me, take it aggressively, do not step backward and don't allow the ball drop, even it mean u have to be very close to the net and the ball hit you.
Let them lob, not everyone lob well when u rush them!
