Martin Luther Must Have Read Juggling Elephants
Now that I have your attention-yes, I realize Martin Luther lived many centuries ago. However, even then he knew the importance of balancing rewards and feedback. While his focus in the following quote was on child rearing (and remember, this is his perspective), the same principle applies-we must not always be telling people what they are doing wrong... we must just as passionately encourage them when they do something right.
Spare the rod and spoil the child-that is true. But, beside the rod, keep an apple to give him when he has done well.
-Martin Luther
