We lie to ourselves about personal anger. We see it as a problem that we should fix soon, and given enough time we’ll cool off and be better. Almost no one admits that anger is also self-indulgent. It feels good, makes us secure, and gives us something to cling to.
Anger is addicting. It allows us to execute vengeance on people in our heads, or sometimes in reality. It furthers the illusion of control. Sometimes it simply gives the bored something to do.
There’s another kind of anger, for the sake of others. This kind of anger provokes us to action and rallies us to act against injustice, even if it costs us something.
Try not to confuse the two. I can’t tell you how many times I’ve blamed my temper on “righteous” anger. They aren’t the same!
