I heard a while back of a study that was done some years ago. Evidently, they took children preschool or kindergarten, don't remember which, and told them that they could have either 1 piece of chocolate now, or if they waited till the end of the day they could have two. They kept track of which kids took the immediate chocolate and which ones held out for two.
After the kids were grown, they compared the two groups. The ones who held out for two pieces showed less occurrences of mental illness, indebtedness, unhappiness, and overall they were more successful. What do you make of this? Which group are you in?
