Stanford Marshmallow Experiment

May you google on the subject later on, but just to give you a short insight and make you curious, a brief description of an experiment realized by the - anyway known for its controversial experiments (Stanford Prison Experiment, f.e.) - Stanford University (found on kaganonline.com)
In one of the most amazing developmental studies ever conducted, Walter Michel of Stanford created a simple test of the ability of four year old children to control impulses and delay gratification. Children were taken one at a time into a room with a one-way mirror. They were shown a marshmallow. The experimenter told them he had to leave and that they could have the marshmallow right then, but if they waited for the experimenter to return from an errand, they could have two marshmallows. One marshmallow was left on a table in front of them. Some children grabbed the available marshmallow within seconds of the experimenter leaving. Others waited up to twenty minutes for the experimenter to return. In a follow-up study (Shoda, Mischel, & Peake, 1990), children were tested at 18 years of age and comparisons were made between the third of the children who grabbed the marshmallow (the "impulsive") and the third who delayed gratification in order to receive the enhanced reward ("impulse controlled").
The third of the children who were most impulsive at four years of age scored an average of 524 verbal and 528 math. The impulse controlled students who scored 610 verbal and 652 math! This astounding 210 point total score difference on the SAT was predicted on the basis of a single observation at four years of age! The 210 point difference is as large as the average differences between that of economically advantaged versus disadvantaged children and is larger than the difference between children from families with graduate degrees versus children whose parents did not finish high school! At four years of age gobbling a marshmallow now v. waiting for two later is twice as good a predictor of later SAT scores than is IQ. Poor impulse control is also a better predictor of later delinquency than is IQ (Block, 1995).
What I consider interesting in detail is, how one's future is affected by the things, he learned up to his only 4 years!
So, what would you have done?
