From serenityrecovery.org, this is a short but very helpful read about the addictive quality of anger. “Signs of Anger Addiction.”
Definitely applies to us environmental activists; has a bearing not only on our personal health but also very much on the quality and effectiveness of our activism.
“Similar to other addictions like gambling, extreme sports, or even drugs like cocaine the brain releases a dopamine reward when you’re angry which clouds your judgment and can lead to terrifying consequences” (emphasis mine).
