Have you ever had a boss who flies off the handle or a parent who would yell at you when you made a mistake? Did you learn anything from them when they did this or did you find yourself not wanting to bring attention to yourself, so any mistake you made, you would try to hide it?
You need to be less critical of spouses, children, and coworkers when they make mistakes. A world-class pianist will only become that way from continually making mistakes, only then can they create beautiful music.
“Getting angry with people for making mistakes will not teach them to not make mistakes, it just teaches them to hide them.”
