Interesting self-observation.. kudos.

I do the same thing, and I think most people do. For me, I am highly critical of my actions because I perceive that others are just as critical - however, like you, I think I have gradually realized that most people are far more critical of themselves than the are of me. Bearing this in mind, when I make mistakes, I now try to smile enigmatically and imply that I meant to do that. My cats taught me how to do it, and it seems to work quite well. :-)
