Impulse control is not simply delay of gratification. It is the management of one’s knee-jerk reactivity—the attenuation of one’s emotional response to a stimulus. It is damage control in advance.
Approach threatening or risky situations with caution. Develop a self-awareness of your emotional response to a threatening or hostile stimulus. Learn to anticipate the consequences of your possible actions before reacting to the stimulus. Learn to calm yourself, so that your response is more measured and appropriate.
While impulse motivates immediate action before analysis, your control of impulse enables the best action after analysis.
