Great introduction to a wealth of insights. I remember telling myself similar things when recovering from bouts of “indignation” but having your thoughts available to read was quite useful.
I believe I have a right to my anger as long as it doesn’t harm others. After all, it is an emotion that evolved as a means of protection: you cannot face a predator if you don’t psych yourself up for a fight. These days though, what matters is having the means to then argue in a civil way, expressing your anger.
