You allow your ego to take control of your life, as you surrender to it, as a safety mechanism for your insecurity. You may think that you’re not good enough, you don’t measure up, so you create a mask of diversion.
Your ego protects you as you pretend how great you are. You genuinely think you’re simply better than everyone else.
What the ego in humans is in charge of, is mediating immediate impulses and desires. Much like a circus squawker, with responsive action which believes are socially acceptable.
