There is good news here: Human beings will become free from making mistakes on the day that cars will begin to drive themselves.
You are not immune to mistakes and you should know that very well. It is however totally out of place when you refuse to acknowledge your mistakes when they are real. That attitude is termed "unhealthy ego".
The pencil, an inscriptional tool also knows this very well it is likely to make mistakes on paper, therefore behind it is an eraser that helps clean the faulty marks.
What are your erasers? How often do you say, "I am sorry"; do you always want to win every argument on earth even if illegal?
You need to know that humans are fallible. And no vaccine to give you a protection against mistakes; but the cure is there! The cure concerned your approach in periods of conflict.
* This attitude.. "I am right, but I may be wrong"!
