I think that deep down, maybe unconsciously, most will feel that if you admit you made a mistake then you are at fault. Which gives the feeling of "less than" a desired person should be and the fear of being a "faulty human" comes to mind. While I think this is a classic case of "all in your head" for most, it is still a very powerful feeling of not being "good enough" of a person to have faults. Now I don't believe this by anyone who makes mistakes, but I can sure attest that these feelings of "less than" and "not good enough" will go through my head each and every time I make a mistake. I enjoyed reading your post, thank you for sharing it with all of us.
