Negative visualization

Anger is a natural, adaptive response to threats; it inspires powerful, often aggressive, feelings and behaviors, which allow us to fight and to defend ourselves when we are attacked. A certain amount of anger, therefore, is necessary to our survival.
But do not defend yourself by attacking the person who is making you angry.
Because there is a better way.

(When you first rise in the morning tell yourself:" I will encounter busybodies, ingrates, egomaniacs, liars, the jealous, and cranks. They are all stricken with these afflictions because they don’t know the difference between good and evil. Because I have understood the beauty of good and the ugliness of evil, I know that these wrong-doers are still akin to me … and that none can do me harm, or implicate me in ugliness. Marcus Aurelius)
