Impulses are the antithesis of self-discipline. They are unpredictable urges that can take over at any point. Studies have shown that impulses are stronger during emotional reactions. Thus, battling impulses is about putting as much time as possible between an emotional reaction and the actual response you give. Delaying tactics, in other words. You can use the 10 second/minute rule, label your feelings, write down the facts of a situation without regard to your personal perspective, and ask “why” five times to understand the root of the impulse.
