In 2005, we discovered that self-control "outdoes" talent in predicting academic success during adolescence. Since then, a surfeit of longitudinal evidence has affirmed the importance of self-control to achieving everyday goals that conflict with momentary temptations. In parallel, research that has "lumped" self-control with other facets of Big Five conscientiousness has shown the superior predictive power of this broad family of individual differences for diverse life outcomes. Self-control can also be "split" from related traits that in certain contexts demonstrate superior predictive power for achievement. Most important, both the "lumping" and "splitting" traditions have enhanced our understanding of the underlying mechanisms and antecedents of self-control. Collectively, progress over the past decade and a half suggests a bright future for the science and practice of self-control.
