For the heck of it, I plugged "anger" into Wikipedia -- fascinating stuff.
Anger is an emotion related to one's psychological interpretation of having been offended, wronged or denied and a tendency to undo that by retaliation. Videbeck describes anger as a normal emotion that involves a strong uncomfortable and emotional response to a perceived provocation. R. Novaco recognized three modalities of anger: cognitive (appraisals), somatic-affective (tension and agitations) and behavioral (withdrawal and antagonism).
It goes on to say that anger promotes adrenalin and noradrenalin, and I think most of the other stress hormones too (cortisol, etc). It also comes with increased heart rate and blood pressure.
I think... that's not necessarily all bad, if you can harness it. Probably channeling right away the increased bloodflow, heartrate, and stress/alertness hormones into heavy exercise (weight training, sprinting, etc) could let you use it, while getting some counterbalancing dopamine going on, and burning off some of the excess strength and aggression.
There's calming techniques, which can work, but you could also just use it. Anger isn't necessarily all bad, if harnessed correctly into, say, exercise and then routine work where moving at a fast pace and not needing good judgment can work for you.
Have you ever had an incredibly amazing day or week, with huge breakthroughs… and then thought it would be permanent, when it wasn't?
I've spent immense time investigating this phenomenon. It's as aggravating as anything else imaginable. You're flying along, doing incredibly well, it seems like you've turned up to a higher level of production, productivity, creativity, teamwork, whatever -- only to sink back down, and sometimes worse than before for a while.
What causes this?
Well, there's old fashioned complacency or overconfidence -- which is why Tokugawa Ieyasu made his famous quote that, "after victory, tighten the straps on your helmet."
I'm writing about this because we sidetracked a post in the forums and I thought it was interesting to warrant a full article. It's not so much that I want to ram my opinion down the throats of those who disagree with me (I do), but that I feel like my position is misunderstood and I probably didn't do a great job of explaining it.
I don't ever get angry. That doesn't mean that bad things don't happen to me (they do), but most people I know will tell you that they've never seen me angry.
The common misperception is that I don't deal with anger and I stuff it down somewhere. The theory continues that eventually I won't be able to contain it and I will unleash my rage. Or that I'll suddenly become depressed.
