But seriously folks, check out this post by Ed Welch, it's convicting. Here's a teaser from the first line of his post:
The problem with anger is that those who don’t have the problem take it to heart; those who are angry are confident in their right-ness and over time can become massively, utterly, completely deluded, blind and (this is no exaggeration) can feel quite good about themselves after bludgeoning someone close them, as if they have set the world aright. Arrgghh. I hate anger.
