It depends what you do with your time off. Practice your receiving, blocking, game "calling". Do you catch 2 handed or one handed? Do you shift your feet when playing catch? What are your goals, motivations.
Read about the great catchers = Bench, Yogi. Is there a "common tread"?
Watch the eyes of Maldonado [Astros] when he catches. They are constantly moving to the runner on 1st to the hitter.
Study U - tube. Learn the game!!!
