Think about it, what makes you angry? If a coworker doesn’t obey your order, what makes you angry?

If you lose at a game, what makes you angry?

In many situations our anger is pointed towards others, but if you look closely it’s strictly connected to our ego.
Our self-image being lowered, our position being altered, our esteem being attacked.

If we didn’t care, we wouldn’t be angry.
We’re angry because we put ego first.
