Delayed gratification
Interestingly, the children who were best able to delay gratification subsequently did better in school and had fewer behavioral problems than the children who could only resist eating the cookie for a few minutes—and, further, ended up on average with SAT scores that were 210 points higher. As adults, the high-delay children completed college at higher rates than the other children and then went on to earn higher incomes. In contrast, the children who had the most trouble delaying gratification had higher rates of incarceration as adults and were more likely to struggle with drug and alcohol addiction.
