It is easy to recognize Ego’s behavior in others. You don’t have to say anything or act superior because of what you can see. Just quietly observe.
After you see other people’s Ego, the next step is to recognize it in yourself. This is the hard part, to admit that you acted in an immature, shameful way.
It’s hard because it hurts your Ego. Humbling experiences knock the Ego down and keep it in check. This is the built in safety mechanism that does not let the Ego get completely out of control, so be thankful for your humbling experiences.
