Righteous Anger
There is no such thing as righteous anger.
The situation is either
Not worth worrying about
Worth worrying about, because you need to change your perspective
Worth worrying about, because you need to change the world
In all of these situation, being angry will not help you.
Once you have controlled your raging emotions, you can accept the challenges as they come, and respond to adversity with intention. This will allow you to make the best showing, bringing all of your skills and resources to bear.
You can still show emotion, but act from a position of cool, calm and collected.
