I always swing at the ball with all my might. I hit or miss big and when I miss I know it long before the umpire calls a strike on me, for every muscle in my back, shoulders and arms is groaning, "You missed it." And believe me, it is no fun to miss a ball that hard. Once I put myself out of the game for a few days by a miss like that.
