Self-control, morality, and human strength

Self-control refers to the self's ability to alter its own states and responses, and hence it is both key to adaptive success and central to virtuous behavior, especial ly insofar as the latter requires conforming to socially desirable standards instead of pursuing selfish goals. Recent evidence suggests that self-control operates like a strength: It is weaker after an exertion, replenishes with rest, and slowly becomes stronger with repeated exercise. It has multiple links to personal well-being and reduced social problems.
