I did nor realize that the Stanford professor conducted a second study. This time, he offered the children a marshmallow with the promise of a second one upon his return. However, he had control groups as well. Group 1 was to imagine that the marshmallow was like a cloud: round, white and puffy. Group 2 was to imagine how sweet and chewy and soft the marshmallows were. Group 3 was to focus on another tasty treat: crunchy, salty pretzels. Picturing the pretzels produced the longest delay in gratification. The professor concluded that the most effective way to delay gratification is to focus on another pleasure (unavailable at the time).
Regardless of how you delay gratification, the point is that high-delay children lead to happier, more successful adults. In this instant gratification society, it is difficult to resist the urge to go for the quick fix. Learn how to control your impulses. Remember: "Good things come to those who wait".
