Another way to understand the GMP is this: What gets rewarded is what gets done OR what is being done is what is being rewarded. When we think of rewards some will automatically think of monetary rewards. Of course, this is one of the most powerful kind of rewards, but it is often impractical to reward with money. Take for instance the behavior of individuals arriving late for church. You could pay them to arrive on time but there probably isn't enough money available for that to last long.
Rewards don't have to be money. Now that that is settled, begin to think creatively of different kinds of rewards. One of the most powerful in the non-money category is appreciation. Most people crave appreciation, genuine sincere appreciation, desperately. In fact if the appreciation is genuine it can be a powerful force for changing behavior. On the other hand if it is perceived to be insincere and manipulative behaviors will get even worse.
Remember when you identify behavior patterns to connect the dots to the reality that what is being done is what is being rewarded, whether you think so or not. To change the behavior, figure out what behavior you want, and then design a way to reward that behavior. . . and be patient, it will change.
