How to develop a sense of patient decisiveness during a ping pong game?

Some players are too patient they mostly just keep the ball in play, missing opportunities to score. Others are too decisive they jump on every ball with little patience or judgment. Develop a sense of "patient decisiveness" in other words, pick your shots carefully, but once you've made a decision, be decisive about it. Don't be afraid to take a shot, but don't be afraid not to take a shot when it's not there. Be decisive about whatever shot you choose.
