To manage one's impulsivity, one must act with forethought and deliberation rather than reacting impulsively or engaging in efforts without a plan.
"...[G]oal directed self-imposed delay of gratification is perhaps the essence of emotional self-regulation: the ability to deny impulse in the service of a goal, whether it be building a business, solving an algebraic equation, or pursuing the Stanley Cup."
