Anger. What a silly thing.
Is it of any use? Nope, it unbalances you.
The orcs in the Lord of the Rings are driven by fury and are utterly useless at combat.
Energy from anger is polluted, destructive, counter-productive.
It can be used to instil fear, to incite others and to self-aggrandise – which is why it has been the emotion of choice by demagogues and sociopaths.
It is often learned as the default response to any frustration.
There is often anger at other people for not behaving as it is believed they should.
The reality however is that you have no real idea what has and is happening in the other person’s life you are judging.
The fact is you only ever see a tiny aspect of all the parts in motion.
