I've been told anger is a secondary emotion. Anger is really a reaction to our reaction. We are sad at the loss of someone close to us so we become angry at the world that took them. We are embarrassed by a friend so we become angry at the source of our embarrassment. The theory makes sense and whenever I'm angry, it helps so much to consider what is going on underneath the surface. It's wild how quickly I can get worked up without even understanding why.
Today it was raining and I had a tough hour at work so I took a drive and listened to some Birdtalker as I considered why I was really angry. How had I hurt or been hurt? I've found that's almost the cause of my anger. I'm either hurt by another or disappointed with how I acted. Both those deeper truths are far more actionable than anger. Anger usually leaves only a couple options open, though sometimes those are the best options. Self-compassion and empathy though, widen the playing field considerably. Many times, there are constructive creative options where all win that we aren't able to see when angry. Or at least that's what I tell myself.
