O my God, what must a soul be like when it is in this state! It longs to be all one tongue with which to praise the Lord. It utters a thousand pious follies, in a continuous endeavor to please Him who thus possesses it.

Listening and hearing are two different things, and acting is comprehending what the person is saying, thinking how it makes you feel and responding. That's the key to really honest, truthful, compelling performance.
