I don't know a soul who has not suffered.
Not that I'm good at it but I hear the trick is to not mind that it hurts.

What if there is a person who is conditioned to feel embarrassed far too often. Every time they feel a cringe worthy moment they react to it with a self rage.

What if they instead react with a 'so what no body's perfect'?

That seems like a realistic way to relax and forgive one's self.

A person without a self conscious or empathy is a social psychopath who is not inherently dangerous , they just don't care enough to have a cringe worthy moment. They would think that others are just pawns to manipulate.
